Jet is a type of lignite , the lowest rank of coal , and is a gemstone . Unlike many gemstones, jet is not a mineral , but is rather a mineraloid . It is derived from wood that has changed under extreme pressure.
56-675: The Yorkshire Coast runs from the Tees estuary to the Humber estuary, on the east coast of England . The cliffs at Boulby are the highest on the east coast of England, rising to 660 feet (200 m) above the sea level. The North York Moors National Park extends up to the coastline and traverses 26 miles (42 km) of it between Boulby and Cloughton, taking in the historic fishing villages of Staithes , Runswick Bay and Robin Hood's Bay . The section of coastline south of Bridlington to Spurn Head
112-485: A Megalosaurus ), was discovered in April 2021. The fossil dates the dinosaur to living around 175 to 164 million years ago. Spurn is a peninsula that extends southwards from the south eastern edge of Holderness . It is 3.5 miles (5.6 km) long and in places is only 160 feet (50 m) wide. It is continually being eroded by the sea and also becomes a dumping ground for sand, pebbles and rocks washed down from further up
168-548: A specific gravity of 1.30 to 1.34. The refractive index of jet is approximately 1.66. The touch of a red-hot needle should cause jet to emit an odour similar to coal. Jet may induce an electric charge like that of amber when rubbed. Jet is very easily cut using carving tools, but small pieces tend to break off, making it difficult to create fine details. It therefore takes an experienced lapidarist to execute more elaborate carvings. The jet found at Whitby , in England,
224-401: A black as possible, derives from this material. Jet is a product of decomposition of wood from millions of years ago, commonly the wood of trees of the family Araucariaceae . Jet is found in two forms, hard and soft. Hard jet is the result of carbon compression and salt water; soft jet may be the result of carbon compression and fresh water. Despite the name they both occupy the same area of
280-491: A few jewellers in work, but by the end of World War II only three remained, and the industry died out completely with their deaths. In Whitby the Victorian tradition continued up until the aftermath of World War II. Jet jewellery (both vintage and new) was then to remain out of fashion until the late '70s. In the '80s there was a fashion for jet beads and antique jet jewellery started to rise in value. New jewellers took up
336-481: A gemstone became fashionable during the reign of Queen Victoria . It originally became fashionable in the 1850s after the queen wore a necklace of it as part of mourning dress for Princess Victoria of Saxe-Coburg and Gotha . Later the Queen wore Whitby jet as part of her mourning dress while mourning the death of Prince Albert . In some jewellery designs of the period jet was combined with cut steel . Jet use
392-471: A prominent theme. The source of the jet has not been confirmed although Whitby is the most likely possibility. Medieval jet use appears to have been largely limited to religious items such as crosses and Rosary beads. During the period there was a belief that water drunk from jet bowls could help with labour . A jet bowl held in the Museum of London may have been designed to allow for this. Jet became
448-477: A valued costume accessory in the 16th century. Mary, Queen of Scots , owned jet buttons and clothes embroidered with jet beads. Elizabeth I bought 1000 "black jet bugle drops" to embroider headdresses in 1587. Anne of Denmark ordered a gown of "double burret" silk in June 1597 loaded with jet passementerie and 360 jet buttons. The gown was too heavy to wear and she ordered it to be remade with less jet. Jet as

After a prolonged rainfall, water had seeped into the earth which destabilised the ground underneath the hotel causing a landslide. Television cameras managed to capture the building falling onto the shoreline below. Part of the coastal geological make-up in North Yorkshire is Whitby Jet . Jet is a hard Lignite mineraloid that
560-619: Is also known as the Holderness coast, from the area of East Yorkshire it adjoins. In 2016, Natural England announced the creation of a coastal path between Filey Brigg and Newport (Middlesbrough) Transporter Bridge. This will eventually link up with paths all around the coastline of England to become the England Coast Path. The section from Filey to Saltburn is in use as part of the Cleveland Way. The coastline between

The earliest known worked jet object is a 10,000 BC model of a botfly larva, from Baden-Württemberg, Germany, found among the Venuses of Petersfels . Jet has been used in Britain since the Neolithic period It continued in use in Britain through the Bronze Age where it was used for necklace beads. Jet necklaces following the plate and spacer design may have been based on Gold lunula . During
728-457: Is superficially similar to fine jet, and has been used to imitate it. This imitation is not always easy to distinguish from real jet. Some museums have produced reproductions of jet artefacts in epoxy resin . Unlike black glass , which is cool to the touch, jet is not cool, due to its lower thermal conductivity . When rubbed against unglazed porcelain, true jet will leave a brown streak , although bog oak , vulcanite , and lignite will do
784-857: Is the "Jet Rock" unit of the Mulgrave Shale Member, which is part of the Whitby Mudstone Formation . This jet deposit was formed approximately 181 million years ago, during the Toarcian age of the Early Jurassic epoch. Whitby Jet is the fossilized wood from species similar to the extant Chilean pine ( Araucaria araucana ). The deposit extends throughout North York Moors National Park . Jet has also been found in Kimmeridge shale seams in Dorset. Jet

The northernmost Heritage Coast has a footpath alongside its entire length (the seaward side of the Cleveland Way ). The North Yorkshire and Cleveland Heritage Coast designation does not include the coastal section around Whitby (Upgang Chine to Abbey Field) as it has been built on and developed. As can be seen from
896-515: Is to be found in the waters of the Yorkshire coast. Fishing fleets large and small are located at many of the ports on the coastline with Whitby, Scarborough, Filey and Bridlington being prime examples of ports which historically hosted larger fleets. Bridlington is the largest shell fishing port in the British Isles and exports its catches to the continent, most oftentimes being France, Italy and Spain. Smaller scale operations also exist such as
952-562: The Iron Age jet went out of fashion until the early 3rd century AD in Roman Britain . The end of Roman Britain marked the end of jet's ancient popularity. Early archaeologists (particularly Victorian) often failed to distinguish between jet and other jet-like materials In particular in southern Britain the material described as jet was often Kimmeridge Shale . and some artifacts use more than one jet-like material. For example
1008-565: The Pen y Bonc necklace combines two or three jet pieces with other dark material. Whitby jet was a popular material for jewellery in Roman Britain from the 3rd century onward. There is no evidence for Roman jet working in Whitby itself, rather it was transferred to Eboracum (modern York ) where considerable evidence for jet production has been found. The collection of jet at this time
1064-656: The Sea Life Centre at Scalby Mills , Scarborough Castle and Whitby Abbey which on its own attracts more than 150,000 visitors annually. Pleasure cruises are available from Bridlington and Scarborough to allow visitors to see the coast from the sea and for sea fishing tours. The coastline plays host to many beaches, be they sandy or rocky. As of 2016, just four of the beaches along the coast have been awarded Blue Flag status; Whitby West Cliff, Scarborough North Bay, Bridlington North Beach and Hornsea. Redcar & Cleveland Borough Council have responsibility for one of
1120-627: The Camino de Santiago. However, the deposits were in Asturias, where simple objects such as beads and rosary beads were also made. Santiago de Compostela was the main sales point and the location of the workshops that produced artistic objects. Jet has also been extracted in the area of Utrillas, Gargallo, and Montalbán in the province of Teruel, although it is of lower quality than that from Asturias. Native American Navajo and Pueblo tribes of New Mexico were using regionally mined jet for jewelry and
1176-465: The Derwent in 1799, a river was carved out from Mowthorpe to Scalby which allows floodwaters to drain to the sea, thereby sparing the riverside further downstream. The Sea Cut , as it is known, was completed in 1804 and roughly follows the route that waters used to drain eastwards towards the sea before the last Ice Age and the Derwent river headed inland. An average of 1.4 million people visit
