Villiaumite and Tanzanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Villiaumite and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Villiaumite and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Villiaumite is 3.35 whereas that of Tanzanite is 3.35.
