Chrome Diopside Facet and Polishing Info
Chrome Diopside is not treated. Unlike most other gems, which are heated, irradiated or oiled -- there is absolutely NO treatment given to chrome diopside.
Chrome Diopside is in the pyroxene group of minerals, and has PRISMATIC CLEAVAGE, which means the angles of cleavage are 87 degrees and 93 degrees (almost perpendicular). This makes it a very difficult gem to facet. But at the same time, it has about twice the refraction of an emerald, giving it a brilliant sparkle.
We also do checkerboard cutting.
