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