Tremolite and Spinel Specific Gravity

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