What is Bronzite? 

Bronzite is a member of the mineralogical chemical series that includes Hypersthene. The color of Bronzite is green or brown, with schillar (a metallic sheen) that gives it a bronze-like appearance. For gemstone use, it is usually cut en cabochon, and it is also carved for small ornamental items. Some Bronzite has a fairly distinct fibrous structure, and when this is pronounced, the sheen has a resemblance to cat’s eye. The general use of Bronzite as  gemstone is less extensive than that of its mineralogical cousin, Hypersthene.
