Oligoclase and Tanzanite Specific Gravity

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