Jet
Mohs Scale 2.5 to 4
A fascinating, lightweight and historically rich gemstone. Often classified as a mineraloid, originating from decomposed, compressed and fossilized wood under extreme pressure. Comprised of 75% carbon, with oxygen, hydrogen and sulfur, it is piezoelectric, meaning it can make a charge when rubbed. Renowned for its intense black color and often termed 'jet black'. A popular choice in mourning jewelry, called 'Whitby jet' in the Victorian era.
Purifies the aura while grounding and stabilizing emotions.It is often used to break negative habits, alleviate irrational fears and provide comfort during grief. Said to protect against the 'evil eye' (Azabache).
Primarily used in jewelry ranging from cameos to beads and carvings. It is prized for specialized instrument making. Historically, it was powdered and mixed with wine for use on tooth ailments. In Turkey it is used for prayer beads (Oltu stone).
Use & Care
Use: Last On, First Off: Apply all lotions, perfumes, and hair/body sprays before putting on jewelry to prevent chemical buildup that can dull and damage the surface. Activity Check: Remove jewelry before swimming (chlorine), showering (soap residue and chemical exposures), or high impact activities like exercise or gardening to avoid damage. Chemical Exposure: Avoid household cleaners, alcohol-based sanitizers, and vinegar, which can alter appearances permanently.
Cleaning: Method: Use lukewarm water and mild (detergent free) soap. Action: Gently rub with a soft cloth. Drying: Crucial. Immediately pat dry with a soft lint-free cloth. Do not air-dry, as residual moisture can damage porous stones over time. Avoid: Never use ultrasonic or steam cleaners, which can cause fractures and strip some colors.
Storage: Individual Separation: Store each piece in its own soft pouch or a lined compartment to prevent stones and metals of varying hardness scratching each other. Environment: Keep in a cool, dry place away from direct sunlight. Moisture Control: Consider adding silica packets to storage containers to absorb excess humidity that can tarnish metals and affect stones over time.
Longevity: If the stone appears white or flaky, it may be degrading or experiencing "pyrite disease" if pyrite inclusions are present.
