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