Dravite and Lawsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Lawsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Lawsonite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 3.09 whereas that of Lawsonite is 3.09.
