Lawsonite and Foitite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lawsonite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lawsonite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Lawsonite is 3.17 whereas that of Foitite is 3.17.
