- Chemical formula of Quartz- SiO2
Smoky Quartz and Quartz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Smoky Quartz and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Smoky Quartz and Quartz Optical Properties during the identification of gemstone. Specific gravity of Smoky Quartz is 2.65 whereas that of Quartz is 2.65.
