Sillimanite Copper Ring | Fibrolite Cats Eye Ring

Sillimanite Copper Ring

Beautiful AAA quality and rare black Sillimanite Cats Eye (aka Fibrolite) ring in copper. Each perfect little oval stone measures 5 x 7mm.

Among the gemstones that display special optical phenomena, cat's eye gems are particularly interesting, in part because the effect is found in so many different gem varieties. The technical term for the cat's eye effect is chatoyancy, derived from the French for eye of the cat ("oeil de chat").
