Apatite and Ametrine Specific Gravity

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