Dravite and Gaylussite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Gaylussite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Gaylussite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 1.93-1.99 whereas that of Gaylussite is 1.93-1.99.
