Peridot
About
Mohs Scale 6.5 to 7
Known as the 'evening emerald' and as the 'gem of the sun' due to its unique color. This vibrant olive-to-lime-green is derived from peridots orthorhombic crystal system, as well as its chemical composition (iron and magnesium) rather than its impurities, like many gems. This idiochromatic olivine-gemstone is sometimes found in pallasite meteorites, though more commonly in volcanic basalt rocks. It has a relatively dense specific gravity of 3.27-4.37.
Known as the 'stone of compassion, warmth and healing' it is often used for protection from nightmares and negative energies. Peridot is often associated with positive energy, emotional balance and prosperity.
Highly prized as a gem for jewelry and adornment. Only non-gem-grade olivine is used industrially, primarily for furnace linings, sand-blasting abrasive and in steel production slag conditioning.
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: Avoid sudden extreme temperature changes to avoid fracture, which seems funny for a gem that can travel by meteorite.
