Thomsonite and Piemontite Specific Gravity

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