It forms complete solid solution series with hedenbergite (FeCaSi2O6) & augite, & partial solid solutions with orthopyroxene & pigeonite. It forms variably colored, but typically dull green crystals in the monoclinic prismatic class. It has two distinct prismatic cleavages at 87 & 93o typical of the pyroxene series. It has a Mohs hardness of six, a Vickers hardness of 7.7 GPa at a load of 0.98 N,[4]and a specific gravity of 3.25 to 3.55. It is transparent to translucent with indices of refraction of nα=1.663-1.699, nβ=1.671-1.705, & nγ=1.693-1.728. The optic angle is 58o to 63o. Diopside is found in ultramafic (kimberlite & peridotite) igneous rocks, & diopside-rich augite is common in mafic rocks, such as olivine basalt & andesite. Diopside is also found in a variety of metamorphic rocks, such as in contact metamorphosed skarns developed from high silica dolomites. It is an important mineral in the Earth's mantle & is common in peridotite xenolithserupted in kimberlite & alkali basalt. Gemstone quality diopside is found in two forms: the black star diopside & the chrome diopside (which includes chromium, giving it a rich green color). At 5.5-6.5 on the Mohs scale, chrome diopside is relatively soft to scratch. Diopside derives its name from the Greek dis, "twice", & òpsè, "face" in reference to the two ways of orienting the vertical prism. Diopside was discovered & first described about 1800, by Brazilian naturalist Jose Bonifacio de Andrada e Silva. Black Diopside...
