JET

Whitby, North Yorkshire

Fossilised wood extensively used for jewellery
 
A good example of Whitby jet showing its natural state, on a fragment of limestone, with one side polished. The specimen contains veins of calcite.

Jet is a black fossilised wood, known as lignite, that is found in the cliffs of Jurassic limestone and clay on the Yorkshire coast near Whitby.  It was first used for jewellery in Roman Britain but it was particularly fashionable in Victorian times.  It is still used for jewellery today.

Jet dates from the Jurassic period, about 180 million years old, and is the fossilised remains of trees of the family Araucaria or monkey puzzle tree.
