Quartz and Londonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Quartz and Londonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Quartz and Londonite Optical Properties during the identification of gemstone. Specific gravity of Quartz is 3.34 whereas that of Londonite is 3.34.
