Lawsonite and Charlesite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lawsonite and Charlesite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lawsonite and Charlesite Optical Properties during the identification of gemstone. Specific gravity of Lawsonite is 1.79 whereas that of Charlesite is 1.79.
