Oligoclase and Sunstone Specific Gravity

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