Diopside and Shigaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diopside and Shigaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Shigaite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 2.32 whereas that of Shigaite is 2.32.
