Monazite and Quartz Specific Gravity

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