Zincite and Zoisite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zincite and Zoisite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zincite and Zoisite Optical Properties during the identification of gemstone. Specific gravity of Zincite is 3.20-3.50 whereas that of Zoisite is 3.20-3.50.
