Plasma and Howlite Specific Gravity

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