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