Iolite
About
Mohs Scale 7 to 7.5
Known as 'Viking Compass' for its historical use in navigation. A metamorphic rock with distinct one directional cleavage. Iolite displays pleochroism, showing pronounced color change from intense violet-blue, yellow-grey to pale blue, depending on the angle of view.
Associated with guidance, inner vision and unlocking creative inspiration. Believed to clear brain fog, reduce anxiety and promote curiosity.
Iolite is a cordierite (magnesium aluminum silicate mineral) renowned for its exceptional thermal shock resistance, low thermal expansion and high mechanical strength. It is used as a refractory ceramic for kiln shelves, pizza stones and catalytic converter substrates.
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.
