Sillimanite and Tinzenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sillimanite and Tinzenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sillimanite and Tinzenite Optical Properties during the identification of gemstone. Specific gravity of Sillimanite is 3.355-3.433 whereas that of Tinzenite is 3.355-3.433.
