Jet is a geological material formed from fossilized wood — specifically the wood of Araucaria trees that fell into stagnant water millions of years ago. The most famous source is Whitby, England, where jet has been worked since the Bronze Age. Queen Victoria made it famous as mourning jewelry after Prince Albert's death.
Despite being organic, jet takes a brilliant polish and has been valued as a gemstone for millennia. It is remarkably lightweight and warm to the touch, distinguishing it from look-alikes like black glass or onyx.

Jet has been treasured by civilizations for over 10,000 years, with archaeological evidence showing its use in prehistoric jewelry and amulets. The ancient Romans called it 'gagates' after the river Gagas in Turkey where it was found, while the modern name derives from the French 'jaiet.' This fossilized wood, formed from ancient Araucaria trees under specific geological conditions over millions of years, became particularly significant in Bronze Age Britain, where it was carved into intricate beads and pendants.
During the Victorian era, jet experienced its golden age when Queen Victoria popularized mourning jewelry following Prince Albert's death in 1861. The town of Whitby in Yorkshire, England, became the epicenter of jet mining and craftsmanship, producing elaborate mourning jewelry that adorned the bereaved across Europe. Medieval pilgrims wore jet amulets for protection on their journeys to Santiago de Compostela, believing it could ward off evil spirits and negative energies. Ancient peoples from Rome to Tibet incorporated jet into religious ceremonies and burial rites, recognizing its powerful protective properties and connection to the earth's ancient wisdom.
Due to its low hardness of 2.5 on the Mohs scale, jet requires gentle handling to prevent scratches and chips. Clean your jet jewelry with a soft, damp cloth and mild soap, avoiding harsh chemicals, ultrasonic cleaners, and steam cleaning which can damage its organic structure. Store jet pieces separately from harder gemstones, wrapped in soft cloth or kept in individual pouches to prevent abrasion. Avoid prolonged exposure to direct sunlight, which can cause fading, and keep away from excessive heat that may cause cracking. Since jet is lightweight and somewhat porous, avoid soaking it in water for extended periods. When not wearing jet jewelry, store it in a cool, dry place away from perfumes and cosmetics that could stain or deteriorate the surface. Handle with care during activities, as jet can break or chip more easily than mineral gemstones.
Jet resonates particularly well with Capricorn, Scorpio, and Pisces individuals, offering grounding energy that complements these signs' need for emotional stability and protection. Those experiencing grief, major life transitions, or seeking spiritual protection often find jet's ancient wisdom comforting and empowering. Mental health professionals, funeral directors, and anyone working in emotionally challenging environments may benefit from jet's protective and grounding qualities. Highly sensitive individuals who feel overwhelmed by negative energies or those seeking to establish stronger boundaries will find jet's absorbing properties particularly helpful. Artists, historians, and those drawn to ancient wisdom traditions often feel a natural connection to this fossilized material. Jet is also beneficial for those struggling with fear-based emotions or seeking to release ancestral patterns, as its connection to ancient earth energies provides a sense of timeless stability and protection.
