Oligoclase and Pearl Specific Gravity
Another important criteria for qualitative analysis of gemstones is Oligoclase and Pearl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Pearl Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 2.60-2.85 whereas that of Pearl is 2.60-2.85.
