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