Brucite and Agrellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brucite and Agrellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Agrellite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 2.88 whereas that of Agrellite is 2.88.
