Scolecite and Melanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Scolecite and Melanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Scolecite and Melanite Optical Properties during the identification of gemstone. Specific gravity of Scolecite is 3.70-4.10 whereas that of Melanite is 3.70-4.10.
