Rubellite and Quartz Specific Gravity

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