This Iolite crystal sphere has a diameter of 86mm. The weight is 956 grams.
The meaning of its name (Iolite) comes from the Greek word meaning violet. Another name for Iolite is Water Sapphire.
As with any stone, crystal and mineral, there will be natural blemishes and/or imperfections. I have photographed in natural light, without a flash and have tried to show its genuine state in the best way.
