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