Hypersthene gemstones are a greenish rock-forming mineral consisting of magnesium and iron silicate. The word "hypersthene" comes from the Greek word for "over strength," no doubt alluding to the hardness as compared to minerals such as hornblende it was often confused with. "Hypersthene" is not a commonly used term these days, often categorized instead as enstatite or ferrosilite. However, hypersthene is the intermediary between those two minerals. Enstatite contains more magnesium, ferrosilite contains more iron and hypersthene is in the middle with about 50% iron. Hypersthene is typically brown, green or grey with a vitreous to pearly luster. Some hypersthene has been known to display a coppery or red metallic sheen.
