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