The working

  1. Light the candle and place the jet and the photograph or keepsake in front of it.
  2. Hold the jet in your palm. Notice how warm and light it feels compared with glass; that warmth is how jet is told from imitations.
  3. Say the name of the person or the loss you are carrying, and one thing you are grateful for from that time.
  4. If you are not grieving but want protection, say what you are asking to be kept from, as Roman and Spanish wearers did.
  5. Polish the jet with the cloth, then wear it or keep it with the keepsake.
  6. Snuff the candle. Wear the jet on hard days, and take it off and put it away when you feel ready to set the weight down.

Take care: Jet is soft and brittle, so keep it away from heat, harsh cleaners and hard knocks. Never leave the candle burning unattended.

Versions across time and place

Medusa and bear amulets of Roman York

Roman Britain · 3rd and 4th centuries CE

Jet collected near Whitby was worked in York and Malton into rings, beads and pendants. Medusa-head pendants found with young women in Roman York were believed to turn evil away, and small jet bears buried with infants may have been guardians.

Uses: carved jet pendant

Recorded in: Malton Museum, Roman Jet and the Malton Bear; Jet (lignite), Wikipedia
ii

Azabache of Santiago

Spanish and Latin American charm · late Middle Ages to present

At the end of the Middle Ages, Santiago de Compostela became a centre for jet religious objects and amulets sold to pilgrims, made from Asturian jet. In Spain and Latin America an azabache, often a jet fist or bead, is still pinned on babies against mal de ojo.

Uses: azabache charm

Recorded in: Jet (lignite), Wikipedia

Victorian mourning jet

Victorian Britain · 1850s to 1880s

Queen Victoria wore jet in mourning, most famously after Prince Albert died in 1861, and mourning dress made Whitby jet a booming industry that peaked in the early 1870s. Cheaper mourning pieces used black glass called French jet, vulcanite or bog oak.

Uses: jet brooch or beads

Recorded in: Jet (lignite), Wikipedia; GIA, Whitby Jet reading list

History

Jet is a type of lignite formed from wood, much of it from trees related to the monkey puzzle, compressed under the sea about 180 million years ago. The best-known source is the Jet Rock of the Yorkshire coast near Whitby. People in Britain wore jet from the Neolithic, and Bronze Age necklaces of jet beads survive. In Roman Britain jet from Whitby was worked at York and Malton in the 3rd and 4th centuries, into Medusa pendants and animal figures believed to guard against evil.

Santiago de Compostela sold jet pilgrim amulets from the late Middle Ages, and the azabache still guards against the evil eye. Victorian mourning made Whitby jet famous, with over 1,000 workers in Whitby at its peak in the early 1870s, falling to about 300 by 1884. Today it is worn as a protective and grieving stone. Crystal healing has no scientific support: in a 1999 Goldsmiths experiment by Christopher French and colleagues, volunteers holding fake crystals reported the same sensations as those holding real quartz. Black glass, vulcanite, plastic and anthracite are all sold as jet; real jet feels warm and light and leaves a brown streak.
