DIOPSIDE
Not a particularly well known gemstone, Diopside was first described in the early 1800’s and derives its name from the Greek words “dis and “opse”, meaning “two faced”, in reference to the two ways of orienting the gem before cutting (Diopside is unusual in that it has perfect cleavage in two directions).
Due to the presence of iron, the colours of the gem vary from yellow to pale green to dark bottle green. Two of the most popular varieties are Black Star Diopside (normally cabochon cut if the gem demonstrates chatoyancy or asterism) and Chrome Diopside which, as the name suggests, gets its vivid green colours from chromium.
