126-624: The Beau Sancy is a 34.98-carat (6.996 g) diamond originally mined in India, which is cut in a modified pear double rose-cut shape . Since appearing in Europe in the 16th century, the Beau Sancy has been owned by a number of European royal houses, among them the House of Medici and the kings of England and Prussia . After more than 300 years in the possession of the House of Hohenzollern ,
252-819: A subduction zone . Stuart Restoration The Stuart Restoration was the reinstatement in May 1660 of the Stuart monarchy in England , Scotland , and Ireland . It replaced the Commonwealth of England , established in January 1649 after the execution of Charles I , with his son Charles II . The term is also used to describe the reign of Charles II (1660–1685), and sometimes that of his younger brother James II (1685–1688). After Richard Cromwell , Lord Protector from 1658 to 1659, ceded power to
378-491: A Christie's auction. In May 2009, a 7.03-carat (1.406 g) blue diamond fetched the highest price per carat ever paid for a diamond when it was sold at auction for 10.5 million Swiss francs (6.97 million euros, or US$ 9.5 million at the time). That record was, however, beaten the same year: a 5-carat (1.0 g) vivid pink diamond was sold for US$ 10.8 million in Hong Kong on December 1, 2009. Clarity
504-568: A Commonwealth of its own in what is known as Fendall's Rebellion but with the fall of the republic in England he was left without support and was replaced by Philip Calvert upon the Restoration. Virginia was the most loyal of King Charles II's dominions. It had, according to the eighteenth-century historian Robert Beverley Jr. , been "the last of all the King's Dominions that submitted to
630-580: A Dutch fleet and army led to his accession to the English throne as William III of England jointly with his wife Mary II of England, James' daughter. In April 1688, James had re-issued the Declaration of Indulgence and ordered all Anglican clergymen to read it to their congregations. When seven bishops, including the Archbishop of Canterbury, submitted a petition requesting the reconsideration of
756-400: A bargain. Frederick Henry intended the Beau Sancy as a gift for his new daughter-in-law, the 10-year-old Mary, Princess Royal , daughter of Charles I of England , who also happened to be the granddaughter of Marie de' Medici. The stone would remain with the House of Orange for the next years, but Mary pawned the Beau Sancy in 1659 to support her brother Charles II in his quest to regain
882-453: A cigarette lighter, but house fires and blow torches are hot enough. Jewelers must be careful when molding the metal in a diamond ring. Diamond powder of an appropriate grain size (around 50 microns) burns with a shower of sparks after ignition from a flame. Consequently, pyrotechnic compositions based on synthetic diamond powder can be prepared. The resulting sparks are of the usual red-orange color, comparable to charcoal, but show

The Glorious Revolution ended the Restoration. The Glorious Revolution which overthrew King James II of England was propelled by a union of English Parliamentarians with the Dutch stadtholder William III of Orange-Nassau (William of Orange). William's successful invasion of England with
1134-494: A conquest of Oliver Cromwell 's and Charles II's claim to the island was therefore questionable. However, Charles II chose not to restore Jamaica to Spain and in 1661 it became a British colony and the planters would claim that they held rights as Englishmen by the King's assumption of the dominion of Jamaica. The first governor was Lord Windsor . He was replaced in 1664 by Thomas Modyford who had been ousted from Barbados. New England , with its Puritan settlement, had supported
1260-727: A continuum with carbonatites , but the latter have too much oxygen for carbon to exist in a pure form. Instead, it is locked up in the mineral calcite ( Ca C O 3 ). All three of the diamond-bearing rocks (kimberlite, lamproite and lamprophyre) lack certain minerals ( melilite and kalsilite ) that are incompatible with diamond formation. In kimberlite , olivine is large and conspicuous, while lamproite has Ti- phlogopite and lamprophyre has biotite and amphibole . They are all derived from magma types that erupt rapidly from small amounts of melt, are rich in volatiles and magnesium oxide , and are less oxidizing than more common mantle melts such as basalt . These characteristics allow
1386-452: A diamond to fluoresce. Diamonds can fluoresce in a variety of colors including blue (most common), orange, yellow, white, green and very rarely red and purple. Although the causes are not well understood, variations in the atomic structure, such as the number of nitrogen atoms present are thought to contribute to the phenomenon. Diamonds can be identified by their high thermal conductivity (900– 2320 W·m ·K ). Their high refractive index

#17327903941331512-832: A favourite setting was the bed-chamber. Indeed, sexually explicit language was encouraged by the king personally and by the rakish style of his court. Historian George Norman Clark argues: The best-known fact about the Restoration drama is that it is immoral. The dramatists did not criticize the accepted morality about gambling, drink, love, and pleasure generally, or try, like the dramatists of our own time, to work out their own view of character and conduct. What they did was, according to their respective inclinations, to mock at all restraints. Some were gross, others delicately improper....The dramatists did not merely say anything they liked: they also intended to glory in it and to shock those who did not like it. The socially diverse audiences included both aristocrats, their servants and hangers-on, and
1638-661: A former governor of Connecticut, and one of whose sons had been a captain in Monck 's army, went to England at the Restoration and in 1662 obtained a royal charter for Connecticut with New Haven annexed to it. Maryland had resisted the republic until finally occupied by New England Puritans/Parliamentary forces after the Battle of the Severn in 1655. In 1660 the Governor Josias Fendall tried to turn Maryland into
1764-480: A gemstone. Because it can only be scratched by other diamonds, it maintains its polish extremely well. Unlike many other gems, it is well-suited to daily wear because of its resistance to scratching—perhaps contributing to its popularity as the preferred gem in engagement or wedding rings , which are often worn every day. The hardest natural diamonds mostly originate from the Copeton and Bingara fields located in
1890-540: A haven for refugees fleeing the English republic , had held for Charles II under Lord Willoughby until defeated by George Ayscue . When news reached Barbados of the King's restoration, Thomas Modyford declared Barbados for the King in July 1660. The planters, however, were not eager for the return of the former governor Lord Willoughby, fearing disputes over titles, but the King ordered he be restored. Jamaica had been
2016-494: A knighthood by Charles II. Edmund Dunch was created Baron Burnell of East Wittenham in April 1658, but this barony was not regranted. The male line failed in 1719 with the death of his grandson, also Edmund Dunch , so no one can lay claim to the title. The one hereditary viscountcy Cromwell created for certain, (making Charles Howard Viscount Howard of Morpeth and Baron Gilsland) continues to this day. In April 1661, Howard

It controlled its own "army" (of militia) and deposed the Company appointed Governor, electing a replacement. Its Independent Puritans were forced to emigrate, settling the Bahamas under prominent Bermudian settler, sometime Governor of Bermuda, and Parliamentary loyalist William Sayle as
2268-475: A metallic fluid. The extreme conditions required for this to occur are present in the ice giants Neptune and Uranus . Both planets are made up of approximately 10 percent carbon and could hypothetically contain oceans of liquid carbon. Since large quantities of metallic fluid can affect the magnetic field, this could serve as an explanation as to why the geographic and magnetic poles of the two planets are unaligned. The most common crystal structure of diamond
2394-403: A pale blue flame, and continues to burn after the source of heat is removed. By contrast, in air the combustion will cease as soon as the heat is removed because the oxygen is diluted with nitrogen. A clear, flawless, transparent diamond is completely converted to carbon dioxide; any impurities will be left as ash. Heat generated from cutting a diamond will not ignite the diamond, and neither will
2520-592: A recognisable genre. In addition, women were allowed to perform on the commercial stage as professional actresses for the first time. In Scotland, the bishops returned as the Episcopacy was reinstated. To celebrate the occasion and cement their diplomatic relations, the Dutch Republic presented Charles with the Dutch Gift , a fine collection of old master paintings, classical sculptures, furniture, and
2646-554: A relatively high optical dispersion . Most natural diamonds have ages between 1 billion and 3.5 billion years. Most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the Earth's mantle , although a few have come from as deep as 800 kilometres (500 mi). Under high pressure and temperature, carbon-containing fluids dissolved various minerals and replaced them with diamonds. Much more recently (hundreds to tens of million years ago), they were carried to

These playgoers were attracted to the comedies by up-to-the-minute topical writing, by crowded and bustling plots, by the introduction of the first professional actresses, and by the rise of the first celebrity actors. This period saw the first professional female playwright, Aphra Behn . The Restoration spectacular , or elaborately staged machine play , hit
2898-463: A transition between graphite and diamond are well established theoretically and experimentally. The equilibrium pressure varies linearly with temperature, between 1.7 GPa at 0 K and 12 GPa at 5000 K (the diamond/graphite/liquid triple point ). However, the phases have a wide region about this line where they can coexist. At standard temperature and pressure , 20 °C (293 K) and 1 standard atmosphere (0.10 MPa),
3024-467: A very linear trajectory which is explained by their high density. Diamond also reacts with fluorine gas above about 700 °C (1,292 °F). Diamond has a wide band gap of 5.5 eV corresponding to the deep ultraviolet wavelength of 225 nanometers. This means that pure diamond should transmit visible light and appear as a clear colorless crystal. Colors in diamond originate from lattice defects and impurities. The diamond crystal lattice
3150-425: A volcanic rock. There are many theories for its origin, including formation in a star, but no consensus. Diamond is the hardest material on the qualitative Mohs scale . To conduct the quantitative Vickers hardness test , samples of materials are struck with a pyramid of standardized dimensions using a known force – a diamond crystal is used for the pyramid to permit a wide range of materials to be tested. From

It is a literature that includes extremes, for it encompasses both Paradise Lost and the John Wilmot, 2nd Earl of Rochester 's Sodom , the high-spirited sexual comedy of The Country Wife and the moral wisdom of The Pilgrim's Progress . It saw Locke 's Treatises of Government ,
3402-449: Is 0.01% for nickel and even less for cobalt. Virtually any element can be introduced to diamond by ion implantation. Nitrogen is by far the most common impurity found in gem diamonds and is responsible for the yellow and brown color in diamonds. Boron is responsible for the blue color. Color in diamond has two additional sources: irradiation (usually by alpha particles), that causes the color in green diamonds, and plastic deformation of

In January 1661, the corpses of Cromwell, Ireton and Bradshaw were exhumed and hanged in chains at Tyburn . In 1661 John Okey , one of the regicides who signed the death warrant of Charles I, was brought back from Holland along with Miles Corbet , friend and lawyer to Cromwell, and John Barkstead , former constable of
3654-415: Is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite . In graphite, the bonds are sp orbital hybrids and the atoms form in planes, with each bound to three nearest neighbors, 120 degrees apart. In diamond, they are sp and
3780-420: Is aided by isotopic dating and modeling of the geological history. Then surveyors must go to the area and collect samples, looking for kimberlite fragments or indicator minerals . The latter have compositions that reflect the conditions where diamonds form, such as extreme melt depletion or high pressures in eclogites . However, indicator minerals can be misleading; a better approach is geothermobarometry , where
3906-728: Is also indicative, but other materials have similar refractivity. Diamonds are extremely rare, with concentrations of at most parts per billion in source rock. Before the 20th century, most diamonds were found in alluvial deposits . Loose diamonds are also found along existing and ancient shorelines , where they tend to accumulate because of their size and density. Rarely, they have been found in glacial till (notably in Wisconsin and Indiana ), but these deposits are not of commercial quality. These types of deposit were derived from localized igneous intrusions through weathering and transport by wind or water . Most diamonds come from

4032-405: Is another mechanical property toughness , which is a material's ability to resist breakage from forceful impact. The toughness of natural diamond has been measured as 50–65 MPa ·m . This value is good compared to other ceramic materials, but poor compared to most engineering materials such as engineering alloys, which typically exhibit toughness over 80 MPa·m . As with any material,
4158-414: Is called diamond cubic . It is formed of unit cells (see the figure) stacked together. Although there are 18 atoms in the figure, each corner atom is shared by eight unit cells and each atom in the center of a face is shared by two, so there are a total of eight atoms per unit cell. The length of each side of the unit cell is denoted by a and is 3.567 angstroms . The nearest neighbor distance in
4284-402: Is exceptionally strong, and only atoms of nitrogen , boron , and hydrogen can be introduced into diamond during the growth at significant concentrations (up to atomic percents). Transition metals nickel and cobalt , which are commonly used for growth of synthetic diamond by high-pressure high-temperature techniques, have been detected in diamond as individual atoms; the maximum concentration
4410-419: Is formed of layers stacked in a repeating ABCABC ... pattern. Diamonds can also form an ABAB ... structure, which is known as hexagonal diamond or lonsdaleite , but this is far less common and is formed under different conditions from cubic carbon. Diamonds occur most often as euhedral or rounded octahedra and twinned octahedra known as macles . As diamond's crystal structure has a cubic arrangement of
4536-412: Is higher for flawless, pure crystals oriented to the <111> direction (along the longest diagonal of the cubic diamond lattice). Therefore, whereas it might be possible to scratch some diamonds with other materials, such as boron nitride , the hardest diamonds can only be scratched by other diamonds and nanocrystalline diamond aggregates . The hardness of diamond contributes to its suitability as
4662-404: Is hybrid rock with a chaotic mixture of small minerals and rock fragments ( clasts ) up to the size of watermelons. They are a mixture of xenocrysts and xenoliths (minerals and rocks carried up from the lower crust and mantle), pieces of surface rock, altered minerals such as serpentine , and new minerals that crystallized during the eruption. The texture varies with depth. The composition forms
4788-647: Is in the form of micro/nanoscale wires or needles (~100–300 nanometers in diameter, micrometers long), they can be elastically stretched by as much as 9–10 percent tensile strain without failure, with a maximum local tensile stress of about 89–98 GPa , very close to the theoretical limit for this material. Other specialized applications also exist or are being developed, including use as semiconductors : some blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators . The conductivity and blue color originate from boron impurity. Boron substitutes for carbon atoms in
4914-477: Is one of the 4C's (color, clarity, cut and carat weight) that helps in identifying the quality of diamonds. The Gemological Institute of America (GIA) developed 11 clarity scales to decide the quality of a diamond for its sale value. The GIA clarity scale spans from Flawless (FL) to included (I) having internally flawless (IF), very, very slightly included (VVS), very slightly included (VS) and slightly included (SI) in between. Impurities in natural diamonds are due to
5040-797: Is partially oxidized. The oxidized surface can be reduced by heat treatment under hydrogen flow. That is to say, this heat treatment partially removes oxygen-containing functional groups. But diamonds (sp C) are unstable against high temperature (above about 400 °C (752 °F)) under atmospheric pressure. The structure gradually changes into sp C above this temperature. Thus, diamonds should be reduced below this temperature. At room temperature, diamonds do not react with any chemical reagents including strong acids and bases. In an atmosphere of pure oxygen, diamond has an ignition point that ranges from 690 °C (1,274 °F) to 840 °C (1,540 °F); smaller crystals tend to burn more easily. It increases in temperature from red to white heat and burns with
5166-769: Is possible to treat regular diamonds under a combination of high pressure and high temperature to produce diamonds that are harder than the diamonds used in hardness gauges. Diamonds cut glass, but this does not positively identify a diamond because other materials, such as quartz, also lie above glass on the Mohs scale and can also cut it. Diamonds can scratch other diamonds, but this can result in damage to one or both stones. Hardness tests are infrequently used in practical gemology because of their potentially destructive nature. The extreme hardness and high value of diamond means that gems are typically polished slowly, using painstaking traditional techniques and greater attention to detail than

5292-600: Is sometimes also known as the 'Little Sancy' to better distinguish it from its larger sibling. It is unknown when the diamond first reached Europe, but the earliest record of its existence comes when it was acquired by French diplomat Nicolas de Harlay, seigneur de Sancy , most likely in Constantinople , where he was the French ambassador at the court of Sultan Selim II . When de Sancy faced financial difficulties in attempting to raise an army for Henry III of France , he

The expense of mounting ever more elaborate scenic productions drove the two competing theatre companies into a dangerous spiral of huge expenditure and correspondingly huge losses or profits. A fiasco such as John Dryden 's Albion and Albanius would leave
5544-452: Is the chemically stable form of carbon at room temperature and pressure , but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in
5670-454: Is the case with most other gemstones; these tend to result in extremely flat, highly polished facets with exceptionally sharp facet edges. Diamonds also possess an extremely high refractive index and fairly high dispersion. Taken together, these factors affect the overall appearance of a polished diamond and most diamantaires still rely upon skilled use of a loupe (magnifying glass) to identify diamonds "by eye". Somewhat related to hardness
5796-407: The Beau Sancy , but the stone eventually had to be sold to pay for her funeral and assorted other expenses. The buyer was Frederick Henry, Prince of Orange , who acquired the diamond from an Amsterdam gem dealer for the sum of 80,000 florins . While this was undoubtedly a significant expense, court jeweller Thomas Cletcher assessed the stone's value at over 150,000 guilders, making the purchase
5922-643: The Convention Parliament , which met for the first time on 25 April. On 8 May, it proclaimed that King Charles II had been the lawful monarch since the execution of Charles I on 30 January 1649. Historian Tim Harris argues that "Constitutionally, it was as if the last nineteen years had never happened." Charles returned from exile, leaving the Hague on 23 May and landing at Dover on 25 May. He entered London on 29 May 1660, his 30th birthday. To celebrate His Majesty's Return to his Parliament, 29 May

At the Restoration, after much debate in Parliament, he was exempted from the Indemnity and Oblivion Act. In 1662 he was tried for high treason, found guilty and beheaded on Tower Hill on 14 June 1662. The Instrument of Government , The Protectorate 's written constitutions, gave to

Some blocks of the crust, or terranes , have been buried deep enough as the crust thickened so they experienced ultra-high-pressure metamorphism . These have evenly distributed microdiamonds that show no sign of transport by magma. In addition, when meteorites strike the ground, the shock wave can produce high enough temperatures and pressures for microdiamonds and nanodiamonds to form. Impact-type microdiamonds can be used as an indicator of ancient impact craters. Popigai impact structure in Russia may have

Although eventually reaching a compromise with the Commonwealth, the Bermudians dispute with the company continued and was finally taken before the restored Crown, which was keen for an opportunity to re-assert its authority over the wealthy businessmen who controlled the Somers Isles Company. The islanders' protest to the Crown initially concerned the mis-treatment of Perient Trott and his heirs (including Nicholas Trott ), but expanded to include

Their hardness is associated with the crystal growth form, which is single-stage crystal growth. Most other diamonds show more evidence of multiple growth stages, which produce inclusions, flaws, and defect planes in the crystal lattice, all of which affect their hardness. It

On 20 October 1659, George Monck , the governor of Scotland under the Cromwells, marched south with his army from Scotland to oppose Fleetwood and Lambert. Lambert's army began to desert him, and he returned to London almost alone whilst Monck marched to London unopposed. The Presbyterian members, excluded in Pride's Purge of 1648, were recalled, and on 24 December

Kimberlites can be found in narrow (1 to 4 meters) dikes and sills, and in pipes with diameters that range from about 75 m to 1.5 km. Fresh rock is dark bluish green to greenish gray, but after exposure rapidly turns brown and crumbles. It

9198-595: The Usurpation". Virginia had provided sanctuary for Cavaliers fleeing the English republic . In 1650, Virginia was one of the Royalist colonies that became the subject of Parliament's An Act for prohibiting Trade with the Barbadoes, Virginia, Bermuda and Antego . William Berkeley , who had previously been governor up until 1652, was elected governor in 1660 by the House of Burgesses and he promptly declared for
9324-466: The army restored the Long Parliament . Fleetwood was deprived of his command and ordered to appear before Parliament to answer for his conduct. On 3 March 1660, Lambert was sent to the Tower of London , from which he escaped a month later. He tried to rekindle the civil war in favour of the Commonwealth by issuing a proclamation calling on all supporters of the " Good Old Cause " to rally on
9450-462: The atoms form tetrahedra, with each bound to four nearest neighbors. Tetrahedra are rigid, the bonds are strong, and, of all known substances, diamond has the greatest number of atoms per unit volume, which is why it is both the hardest and the least compressible . It also has a high density, ranging from 3150 to 3530 kilograms per cubic metre (over three times the density of water) in natural diamonds and 3520 kg/m in pure diamond. In graphite,
9576-420: The atoms, they have many facets that belong to a cube , octahedron, rhombicosidodecahedron , tetrakis hexahedron , or disdyakis dodecahedron . The crystals can have rounded-off and unexpressive edges and can be elongated. Diamonds (especially those with rounded crystal faces) are commonly found coated in nyf , an opaque gum-like skin. Some diamonds contain opaque fibers. They are referred to as opaque if
9702-527: The battlefield of Edgehill, but he was recaptured by Colonel Richard Ingoldsby , a participant in the regicide of Charles I who hoped to win a pardon by handing Lambert over to the new regime. Lambert was incarcerated and died in custody in 1684; Ingoldsby was pardoned. The restoration was not what George Monck, as an apparent engineer of the Restoration, had intended – if indeed he knew what he intended, for in Clarendon's sardonic words; "the whole machine
9828-410: The bonds between nearest neighbors are even stronger, but the bonds between parallel adjacent planes are weak, so the planes easily slip past each other. Thus, graphite is much softer than diamond. However, the stronger bonds make graphite less flammable. Diamonds have been adopted for many uses because of the material's exceptional physical characteristics. It has the highest thermal conductivity and
9954-512: The carbon source is more likely carbonate rocks and organic carbon in sediments, rather than coal. Diamonds are far from evenly distributed over the Earth. A rule of thumb known as Clifford's rule states that they are almost always found in kimberlites on the oldest part of cratons , the stable cores of continents with typical ages of 2.5 billion years or more. However, there are exceptions. The Argyle diamond mine in Australia ,
10080-436: The coloration, while pure or nearly pure diamonds are transparent and colorless. Most diamond impurities replace a carbon atom in the crystal lattice , known as a carbon flaw . The most common impurity, nitrogen, causes a slight to intense yellow coloration depending upon the type and concentration of nitrogen present. The Gemological Institute of America (GIA) classifies low saturation yellow and brown diamonds as diamonds in
10206-605: The company's wider mismanagement of the colony. This led to a lengthy court case in which the Crown championed Bermudians against the company, and resulted in the company's Royal Charter being revoked in 1684. From that point onwards the Crown assumed responsibility for appointing the Colony's governors (it first re-appointed the last company governor). Freed of the company's restraints, the emerging local merchant class came to dominate and shape Bermuda's progress, as Bermudians abandoned agriculture en masse and turned to seafaring. In 1663
10332-501: The compositions of minerals are analyzed as if they were in equilibrium with mantle minerals. Finding kimberlites requires persistence, and only a small fraction contain diamonds that are commercially viable. The only major discoveries since about 1980 have been in Canada. Since existing mines have lifetimes of as little as 25 years, there could be a shortage of new diamonds in the future. Diamonds are dated by analyzing inclusions using
10458-596: The death warrant in 1649 were living. The regicides were hunted down; some escaped but most were found and put on trial. Three escaped to the American colonies. New Haven, Connecticut , secretly harboured Edward Whalley, William Goffe and John Dixwell, and after American independence named streets after them to honour them as forefathers of the American Revolution. In the ensuing trials, twelve were condemned to death. The Fifth Monarchist Thomas Harrison ,
10584-628: The decades following the war, the Beau Sancy was occasionally exhibited publicly. In 1972 it was shown in Helsinki together with its sibling diamond the Sancy , at which point the two diamonds had been separated for 370 years. The jewel's story with the House of Hohenzollern ends in 2012, when it was put up for auction with Sotheby's by Georg Friedrich, Prince of Prussia . Although the pre-sale estimate had only been between $ 2–4 million, an eight-minute battle between five interested parties ensued, with
10710-598: The decay of radioactive isotopes. Depending on the elemental abundances, one can look at the decay of rubidium to strontium , samarium to neodymium , uranium to lead , argon-40 to argon-39 , or rhenium to osmium . Those found in kimberlites have ages ranging from 1 to 3.5 billion years , and there can be multiple ages in the same kimberlite, indicating multiple episodes of diamond formation. The kimberlites themselves are much younger. Most of them have ages between tens of millions and 300 million years old, although there are some older exceptions (Argyle, Premier and Wawa). Thus,
10836-470: The diamond crystal lattice. Plastic deformation is the cause of color in some brown and perhaps pink and red diamonds. In order of increasing rarity, yellow diamond is followed by brown, colorless, then by blue, green, black, pink, orange, purple, and red. "Black", or carbonado , diamonds are not truly black, but rather contain numerous dark inclusions that give the gems their dark appearance. Colored diamonds contain impurities or structural defects that cause
10962-506: The diamond lattice is 1.732 a /4 where a is the lattice constant, usually given in Angstrøms as a = 3.567 Å, which is 0.3567 nm. A diamond cubic lattice can be thought of as two interpenetrating face-centered cubic lattices with one displaced by 1 ⁄ 4 of the diagonal along a cubic cell, or as one lattice with two atoms associated with each lattice point. Viewed from a <1 1 1> crystallographic direction , it
11088-415: The diamond lattice, donating a hole into the valence band . Substantial conductivity is commonly observed in nominally undoped diamond grown by chemical vapor deposition . This conductivity is associated with hydrogen -related species adsorbed at the surface, and it can be removed by annealing or other surface treatments. Thin needles of diamond can be made to vary their electronic band gap from
11214-648: The diamond was Augusta Victoria , wife of Wilhelm II. The last Kaiser abdicated the throne at the end of the First World War in 1918 and went into exile in the Netherlands , but the stone remained in Berlin . At the end of the Second World War , it was transferred to a bricked-up crypt for safe-keeping, where it was found by British troops and returned to the estate of the House of Prussia. In
11340-736: The diamond was sold in 2012 at Sotheby's auction in Geneva for $ 9.57 million to an anonymous buyer. The Beau Sancy comes from the famous diamond mines around Golconda , now in the Indian state of Telangana . Like its sibling diamond, the Sancy , it is part of the stones collectively known as the Golconda diamonds , which also include the Koh-i-Noor and the Hope Diamond . The Beau Sancy
11466-407: The diamonds' surface cannot be wet by water, but can be easily wet and stuck by oil. This property can be utilized to extract diamonds using oil when making synthetic diamonds. However, when diamond surfaces are chemically modified with certain ions, they are expected to become so hydrophilic that they can stabilize multiple layers of water ice at human body temperature . The surface of diamonds
11592-410: The early 17th-century court masque , though never ashamed of borrowing ideas and stage technology from French opera , the spectaculars are sometimes called "English opera". However, the variety of them is so untidy that most theatre historians despair of defining them as a genre at all. Only a handful of works of this period are usually accorded the term "opera", as the musical dimension of most of them
11718-449: The fibers grow from a clear substrate or fibrous if they occupy the entire crystal. Their colors range from yellow to green or gray, sometimes with cloud-like white to gray impurities. Their most common shape is cuboidal, but they can also form octahedra, dodecahedra, macles, or combined shapes. The structure is the result of numerous impurities with sizes between 1 and 5 microns. These diamonds probably formed in kimberlite magma and sampled
11844-453: The final bid of US$ 9.7 million (equivalent to about $ 12.9M in 2023) coming from an anonymous buyer. Diamond Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic . Diamond as a form of carbon is a tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite
11970-510: The first person found guilty of regicide, who had been the seventeenth of the 59 commissioners to sign the death warrant, was the first regicide to be hanged, drawn and quartered because he was considered by the new government still to represent a real threat to the re-established order. In October 1660, at Charing Cross or Tyburn , London, ten were publicly hanged, drawn and quartered: Thomas Harrison, John Jones , Adrian Scrope , John Carew , Thomas Scot , and Gregory Clement , who had signed
12096-488: The founding of the Royal Society , the experiments and holy meditations of Robert Boyle , the hysterical attacks on theatres from Jeremy Collier , and the pioneering of literary criticism from John Dryden and John Dennis . The period witnessed news become a commodity, the essay develop into a periodical art form, and the beginnings of textual criticism . The return of the king and his court from exile led to
12222-408: The hardness and transparency of diamond, are the reasons that diamond anvil cells are the main tool for high pressure experiments. These anvils have reached pressures of 600 GPa . Much higher pressures may be possible with nanocrystalline diamonds. Usually, attempting to deform bulk diamond crystal by tension or bending results in brittle fracture. However, when single crystalline diamond
12348-455: The highest sound velocity. It has low adhesion and friction, and its coefficient of thermal expansion is extremely low. Its optical transparency extends from the far infrared to the deep ultraviolet and it has high optical dispersion . It also has high electrical resistance. It is chemically inert, not reacting with most corrosive substances, and has excellent biological compatibility. The equilibrium pressure and temperature conditions for
12474-558: The jewel in 1702. Eager to emulate other absolutist monarchs after his self-elevation to the title of King in Prussia just one year earlier, Frederick considered the storied Beau Sancy to be the cornerstone of the Prussian Crown Jewels . Set in the center of a new crown , and worth a reputed 300,000 Reichsthaler , the diamond spoke to the self-made king's aspirations. In 1713, the jewel passed from Frederick to his son,
12600-423: The kimberlites formed independently of the diamonds and served only to transport them to the surface. Kimberlites are also much younger than the cratons they have erupted through. The reason for the lack of older kimberlites is unknown, but it suggests there was some change in mantle chemistry or tectonics. No kimberlite has erupted in human history. Most gem-quality diamonds come from depths of 150–250 km in
12726-459: The king's death warrant; the preacher Hugh Peters ; Francis Hacker and Daniel Axtell , who commanded the guards at the king's trial and execution; and John Cooke , the solicitor who directed the prosecution. The 10 judges who were on the panel but did not sign the death warrant were also convicted. Oliver Cromwell , Henry Ireton , Judge Thomas Pride , and Judge John Bradshaw were posthumously attainted for high treason. Because Parliament
12852-474: The largest producer of diamonds by weight in the world, is located in a mobile belt , also known as an orogenic belt , a weaker zone surrounding the central craton that has undergone compressional tectonics. Instead of kimberlite , the host rock is lamproite . Lamproites with diamonds that are not economically viable are also found in the United States, India, and Australia. In addition, diamonds in
12978-467: The macroscopic geometry of a diamond contributes to its resistance to breakage. Diamond has a cleavage plane and is therefore more fragile in some orientations than others. Diamond cutters use this attribute to cleave some stones before faceting them. "Impact toughness" is one of the main indexes to measure the quality of synthetic industrial diamonds. Diamond has compressive yield strength of 130–140 GPa. This exceptionally high value, along with
13104-591: The melting point of diamond increases slowly with increasing pressure; but at pressures of hundreds of GPa, it decreases. At high pressures, silicon and germanium have a BC8 body-centered cubic crystal structure, and a similar structure is predicted for carbon at high pressures. At 0 K , the transition is predicted to occur at 1100 GPa . Results published in an article in the scientific journal Nature Physics in 2010 suggest that, at ultra-high pressures and temperatures (about 10 million atmospheres or 1 TPa and 50,000 °C), diamond melts into
13230-579: The melts to carry diamonds to the surface before they dissolve. Kimberlite pipes can be difficult to find. They weather quickly (within a few years after exposure) and tend to have lower topographic relief than surrounding rock. If they are visible in outcrops, the diamonds are never visible because they are so rare. In any case, kimberlites are often covered with vegetation, sediments, soils, or lakes. In modern searches, geophysical methods such as aeromagnetic surveys , electrical resistivity , and gravimetry , help identify promising regions to explore. This
13356-469: The normal 5.6 eV to near zero by selective mechanical deformation. High-purity diamond wafers 5 cm in diameter exhibit perfect resistance in one direction and perfect conductance in the other, creating the possibility of using them for quantum data storage. The material contains only 3 parts per million of nitrogen. The diamond was grown on a stepped substrate, which eliminated cracking. Diamonds are naturally lipophilic and hydrophobic , which means
13482-636: The pair being crowned joint monarchs of England in the Glorious Revolution of 1688. The Beau Sancy thus became part of the Crown Jewels of the United Kingdom for the duration of William and Mary's reign. Mary predeceased William in 1694, and when the King died in 1702, the diamond passed back to the House of Orange , since the couple had been childless. As the highest-ranking member of the House, Frederick I of Prussia claimed
13608-401: The possession of Prussia's ruling House of Hohenzollern for the next 179 years, surviving the 1806 invasion of Napoleon and seeing the rise of the kings of Prussia to become German emperors . The Beau Sancy retained its exalted position amongst the crown jewels, but was reset several times as a pendant, which it was customary for the bride to wear at royal weddings. The last Empress to wear
13734-620: The presence of natural minerals and oxides. The clarity scale grades the diamond based on the color, size, location of impurity and quantity of clarity visible under 10x magnification. Inclusions in diamond can be extracted by optical methods. The process is to take pre-enhancement images, identifying the inclusion removal part and finally removing the diamond facets and noises. Between 25% and 35% of natural diamonds exhibit some degree of fluorescence when examined under invisible long-wave ultraviolet light or higher energy radiation sources such as X-rays and lasers. Incandescent lighting will not cause
13860-658: The replacement of the Puritan severity of the Cromwellian style with a taste for magnificence and opulence and to the introduction of Dutch and French artistic influences. These are evident in furniture in the use of floral marquetry , walnut instead of oak, twisted turned supports and legs, exotic veneers , cane seats and backs on chairs, sumptuous tapestry and velvet upholstery and ornate carved and gilded scrolling bases for cabinets. Similar shifts appear in prose style. Comedy, especially bawdy comedy, flourished, and
13986-529: The size of the resulting indentation, a Vickers hardness value for the material can be determined. Diamond's great hardness relative to other materials has been known since antiquity, and is the source of its name. This does not mean that it is infinitely hard, indestructible, or unscratchable. Indeed, diamonds can be scratched by other diamonds and worn down over time even by softer materials, such as vinyl phonograph records . Diamond hardness depends on its purity, crystalline perfection, and orientation: hardness
14112-419: The stable phase of carbon is graphite, but diamond is metastable and its rate of conversion to graphite is negligible. However, at temperatures above about 4500 K , diamond rapidly converts to graphite. Rapid conversion of graphite to diamond requires pressures well above the equilibrium line: at 2000 K , a pressure of 35 GPa is needed. Above the graphite–diamond–liquid carbon triple point,
14238-524: The surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites . Synthetic diamonds can be grown from high-purity carbon under high pressures and temperatures or from hydrocarbon gases by chemical vapor deposition (CVD). Imitation diamonds can also be made out of materials such as cubic zirconia and silicon carbide . Natural, synthetic, and imitation diamonds are most commonly distinguished using optical techniques or thermal conductivity measurements. Diamond
14364-516: The throne, and that the throne was vacant. To fill this vacancy, James's daughter Mary was declared Queen; she was to rule jointly with her husband William, Prince of Orange, who would be king. The English Parliament passed the Bill of Rights of 1689 that denounced James for abusing his power. The abuses charged to James included the suspension of the Test Acts after having sworn as king to uphold
14490-563: The very top of a crown of pearls and diamonds for her coronation in the Basilica of Saint-Denis in 1610. When Henry was assassinated shortly afterward, Marie became regent for her nine-year-old son Louis XIII , who then exiled her in 1617 due to her mismanagement and ceaseless political intrigues. Marie fled France in 1630, and would remain in exile in Cologne until her death in 1642. Despite her debts piling up, Marie managed to hold on to
14616-454: The volatiles. Diamonds can also form polycrystalline aggregates. There have been attempts to classify them into groups with names such as boart , ballas , stewartite, and framesite, but there is no widely accepted set of criteria. Carbonado, a type in which the diamond grains were sintered (fused without melting by the application of heat and pressure), is black in color and tougher than single crystal diamond. It has never been observed in
14742-430: The world's largest diamond deposit, estimated at trillions of carats, and formed by an asteroid impact. A common misconception is that diamonds form from highly compressed coal . Coal is formed from buried prehistoric plants, and most diamonds that have been dated are far older than the first land plants . It is possible that diamonds can form from coal in subduction zones , but diamonds formed in this way are rare, and
14868-519: Was created Earl of Carlisle , Viscount Howard of Morpeth, and Baron Dacre of Gillesland. The present Earl is a direct descendant of this Cromwellian creation and Restoration recreation. On 6 January 1661, about 50 Fifth Monarchists , headed by a wine-cooper named Thomas Venner , tried to gain possession of London in the name of "King Jesus". Most were either killed or taken prisoner; on 19 and 21 January 1661, Venner and 10 others were hanged, drawn and quartered for high treason . The Church of England
14994-518: Was dissolved by Charles II in January 1661, and he summoned his first parliament in Ireland in May 1661. In 1662, 29 May was made a public holiday known to this day as Oak Apple Day. Coote, Broghill and Maurice Eustace were initially the main political figures in the Restoration. George Monck, Duke of Albemarle was given the position of Lord Lieutenant of Ireland but he did not assume office. In 1662 James Butler, 1st Duke of Ormonde returned as
15120-521: Was forced to sell off some of his jewels, among them both Sancy diamonds; the stones received their names after this sale in around 1589. At the same time, Marie de' Medici had been looking to acquire the largest diamonds she could find on the market. Besides being the heiress to the House of Medici and recipient of a massive fortune, Marie had also inherited a love of diamonds from her father, Francesco I de' Medici, Grand Duke of Tuscany . When de Sancy put his jewels up for sale, Marie saw her chance to buy
15246-478: Was infinitely above his strength ... and it is glory enough to his memory that he was instrumental in bringing those things to pass which he had neither wisdom to foresee, nor courage to attempt, nor understanding to contrive". On 4 April 1660, Charles II issued the Declaration of Breda , in which he made several promises in relation to the reclamation of the crown of England. While he did this, Monck organised
15372-512: Was invested in 1666 with the Order of the Garter (which had been bestowed upon him in 1650), and was advanced to a dukedom on 16 March 1665. The Indemnity and Oblivion Act , which became law on 29 August 1660, pardoned all past treason against the crown, but specifically excluded those involved in the trial and execution of Charles I . Thirty-one of the 59 commissioners (judges) who had signed
15498-503: Was made a public holiday, popularly known as Oak Apple Day . He was crowned at Westminster Abbey on 23 April 1661. Some contemporaries described the Restoration as "a divinely ordained miracle". The sudden and unexpected deliverance from political chaos was interpreted as a restoration of the natural and divine order. The Cavalier Parliament convened for the first time on 8 May 1661, and it would endure for over 17 years, finally being dissolved on 24 January 1679. Like its predecessor, it
15624-479: Was overwhelmingly Royalist . It is also known as the Pensionary Parliament for the many pensions it granted to adherents of the King. The leading political figure at the beginning of the Restoration was Edward Hyde, 1st Earl of Clarendon . It was the "skill and wisdom of Clarendon" which had "made the Restoration unconditional". Many Royalist exiles returned and were rewarded. Prince Rupert of
15750-519: Was released and placed under Dutch protective guard. Having no desire to make James a martyr, William, Prince of Orange, let him escape on 23 December. James was received in France by his cousin and ally, Louis XIV , who offered him a palace and a pension. William convened a Convention Parliament to decide how to handle the situation. While the Parliament refused to depose James, they declared that James, having fled to France had effectively abdicated
15876-699: Was restored as the national Church in England, backed by the Clarendon Code and the Act of Uniformity 1662 . People reportedly "pranced around May poles as a way of taunting the Presbyterians and Independents" and "burned copies of the Solemn League and Covenant ". "The commonwealth parliamentary union was, after 1660, treated as null and void". As in England the republic was deemed constitutionally never to have occurred. The Convention Parliament
