Gypsum and Ametrine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gypsum and Ametrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Ametrine Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 2.65 whereas that of Ametrine is 2.65.
