Description
A pyroxene mineral composed of magnesium silicate. Enstatite was first described by G.A. Kenngott in 1855. It occurs naturally in metamorphic rocks and meterorites. The mineral is usually a gray, pale green, or brown in color although a gemstone quality emerald green variety occurs rarely. Weathered enstatite can have a metallic luster and is called bronzite. Enstatite can alter to form Steatite. Steatite may also be heated to form enstatite.
