Poldervaartite and Quartz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Poldervaartite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poldervaartite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Poldervaartite is 2.65 whereas that of Quartz is 2.65.
