Moonstone Cat's Eye Grey Chatoyancy Ring Unisex Sri Lankan Gemstone Ring Size 7

Moonstone can display chatoyancy, an optical phenomenon also known as the "cat's eye" effect, where a narrow band of light appears to move across the stone's surface when it's moved or viewed from different angles. This effect is caused by parallel inclusions within the moonstone. Another effect is adularescence, which is a milky, billowy sheen. Approximate Measurements: USA Size 7
