Sillimanite and Carletonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sillimanite and Carletonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sillimanite and Carletonite Optical Properties during the identification of gemstone. Specific gravity of Sillimanite is 2.45 whereas that of Carletonite is 2.45.
