Brucite and Binghamite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brucite and Binghamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Binghamite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 2.55-2.70 whereas that of Binghamite is 2.55-2.70.
