Brucite and Coral Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brucite and Coral Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Coral Optical Properties during the identification of gemstone. Specific gravity of Brucite is 2.60-2.70 whereas that of Coral is 2.60-2.70.
