Holmquistite and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Holmquistite and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Holmquistite and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Holmquistite is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
