Grey star sapphire ring
Star Sapphires
Star sapphires are a rare variety of sapphire that exhibit a rare asterism under specific lighting. When viewing a star sapphire, a six-rayed star will appear to float across the surface of the stone. The effect is best viewed under a direct light source and while tilting and rotating the stone from different angles. Star sapphires contain unusual tiny needle-like inclusions of rutile. Aligned needles that intersect each other at varying angles produce the rare phenomenon known as asterism.
This ring is named after a good friend, no longer with us.
Caring for Star Sapphires
Star sapphire are 9 on the Mohs Scale, and are typically very durable
For cleaning, it is best to use warm soapy water and a soft cloth. As with most gemstones, avoid ultrasonic cleaners and steamers, especially with fracture-filled star sapphire; vibrations and heat can damage stones.
Always remove gemstone jewellery or gemstones before exercising, cleaning or engaging in harsh physical activities. Do not expose star sapphire gemstones to acid and store them away from other gemstones to avoid scratches.
