Brucite and Austinite Specific Gravity

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