Diaspore and Scolecite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Scolecite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Scolecite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 2.20-2.23 whereas that of Scolecite is 2.20-2.23.
