Diaspore and Zincite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Zincite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Zincite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 5.50-5.90 whereas that of Zincite is 5.50-5.90.
