Oligoclase and Phosgenite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 6.13 whereas that of Phosgenite is 6.13.
