Jet
The Black Guardian of Quiet Mourning
Also known as: Lignite
About the stone
Jet is a lightweight, deep-black organic gemstone formed from ancient wood altered by burial and pressure; it is a type of lignite rather than a true mineral. Its discovery predates written records, with prehistoric ornaments known from Europe, and it became especially fashionable in Victorian mourning jewelry after Prince Albert’s death in 1861. Famous sources include Whitby in Yorkshire, England, and Asturias, Spain, with other occurrences in Poland and the United States. Historical names include gagates and gagat, while Whitby jet identifies its Yorkshire origin; “French jet” is black glass, not genuine jet. In traditional folklore, jet was worn as protection against witchcraft and the evil eye.

Care and handling
Jet is soft, brittle and surprisingly light, so it scratches and chips easily and can crack with sudden temperature changes. Wipe it with a soft, slightly damp cloth and dry it at once; avoid soaking, harsh cleaners, ultrasonic cleaners, heat and prolonged strong sunlight. Store it separately so harder stones do not scratch it.
Individual experiences with Jet vary and are deeply personal. Hold it gently and with respect for memory and loss, and let its quiet darkness offer comfort in whatever way it can.
