Opal
About
Mohs Scale 5.5 to 6.5
A captivating hydrated amorphous mineraloid renowned for its milky-white appearance with internal play of a rainbow of colors. A popular stone steeped in history, often associated with purity, hope and emotional healing. Formed millions of years ago when silica-rich water seeped into underground cavities and cracks in sedimentary rock. As the water evaporated, the silica hardened to opal. A mineraloid (not a mineral) composed of hydrated amorphous silica with a water content of 6% to 10%. Some opals are hydrophane, meaning they can absorb water, temporarily changing their transparency and color intensity. Microscopic silica spheres arrange themselves in grid patterns that diffract light. Smaller spheres (~0.1 micron) produce violets/blues, while larger spheres (~0.2 microns) produce reds. Australia produces over 90% of the world’s precious opal. Most white opal comes from Coober Pedy, other locations include Ethiopia, Brazil and USA. Ancient Romans carried it as a symbol of love and hope, believing it carried all other gems inside it. Arabian legend says it fell from the heavens in lightning flashes. Greek mythology links opals to Zeus’s tears of joy after defeating the Titans. In the Middle Ages, it was believed to cure eye diseases and improve eyesight.
Worn to attract good fortune, enhance imagination and foster creativity. Associated with a sense of calm, mental clarity and spiritual connection. Used for emotional cleansing, relieving stress and soothing racing thoughts. Thought to absorb negative energy, acting as a shield. Often linked with the divine feminine, providing support to mothers during childbirth.
Prized for jewelry, amulets, talismans, mosaics and decor.
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: Due to its fragility, it is often formed into doublets and triplets, using thin layers of other materials to sandwich the opal for strength. As a hydrated stone, it should be protected from impact, extreme temperature changes and chemicals.
