Diaspore and Brucite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diaspore and Brucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Brucite Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 2.39 whereas that of Brucite is 2.39.
