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