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