Oligoclase and Nifontovite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Nifontovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Nifontovite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 2.35-2.36 whereas that of Nifontovite is 2.35-2.36.
