Seraphinite and Dravite Specific Gravity

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