Diopside is one of the most common members of the pyroxene group. Often occurs in metamorphosed limestone (marbles) as generally pale green to gray-green crystals, masses and bubbles / grains associated with humite group minerals, spinel, phlogopite, tremolite and coarse. Can also be pure white and indistinguishable from the enveloping carbonate. Often fluorescent bright powder blue.
The variable colors are caused by the detection of small amounts of Fe (general), Mn, Ti, V, Cr.
There is an interchangeability with Hiddenite, Moldavite, Peridot, Smaragd and Vesuvian
