Chemical Formula: CaMgSi2O6
1) Diopside is an important rock forming mineral in several metamorphic and basic to ultra basic igneous rocks, also found in meteorites. Diopside is a part of an important solid solution series of the pyroxene group. The series includes the minerals hedenbergite, CaFeSi2 O6, and augite, (Ca, Na)(Fe, Mg, Al)(Al, Si)2 O6. A series occurs when ions (in this case iron and magnesium) can freely substitute between each other. Diopside is the magnesium rich end member of the series. The diopside-hedenbergite series is analogous to the amphiobole, tremolite- actinolite series.
2) Diopside has several varieties, including a chromium-rich gem variety called chrome diopside. Violan is rare blue variety found in some localities in Italy. There is also a green "cat's eye" variety that contains minute inclusions, probably of rutile, that reflect light in such a way as to produce a lively linear luminscence within the crystal. Still another variety is quite dark, with included rutile needles aligned so as to produce a 4-rayed star, hence the name star diopside. Ordinary diopside is typically white or green and can have a nice glassy luster. While the color of chrome diopside is much brighter, many specimens of ordinary diopside are also cut for gemstones. Mineral specimens of diopside can be very striking in appearance, and of interest to mineral collectors. Source: Wikipedia
3) The synthetic diopside uses two primary raw materials, sand and lime, and a special binder and catalyst package to economically synthesize a chemically consistent, high purity diopside.
