Holmquistite and Spinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Holmquistite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Holmquistite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Holmquistite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
