Diopside and Holmquistite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diopside and Holmquistite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Holmquistite Optical Properties during the identification of gemstone. Specific gravity of Diopside is 2.95-3.13 whereas that of Holmquistite is 2.95-3.13.
