Williamsite and Poldervaartite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Williamsite and Poldervaartite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Poldervaartite Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.91 whereas that of Poldervaartite is 2.91.
