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