Boleite and Sillimanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Boleite and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Boleite and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Boleite is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
