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