Almandine and Thomsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Almandine and Thomsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Almandine and Thomsonite Optical Properties during the identification of gemstone. Specific gravity of Almandine is 2.25-2.40 whereas that of Thomsonite is 2.25-2.40.
