Phlogopite and Narsarsukite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phlogopite and Narsarsukite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phlogopite and Narsarsukite Optical Properties during the identification of gemstone. Specific gravity of Phlogopite is 2.72-2.83 whereas that of Narsarsukite is 2.72-2.83.
