Hypersthene

(Enstatite-Ferrosilite)

Hypersthene, properly known as Enstatite-Ferrosilite, is normally found in volcanic or high-grade metamorphic rock. It combines and hardens with the minerals Enstatite and Ferrosilite.  Hypersthene is the name given to the mineral when significant amounts of both Iron and Magnesium elements are present since pure Enstatite does not contain any Iron, whilst pure Ferrosillite does not contain any Magnesium.

Please note: All have some degree of luster. However, some where were difficult to catch their luster in all the photographs.  Please let us know if you'd like a quick video of any.
