Phlogopite and Microlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Phlogopite and Microlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Phlogopite and Microlite Optical Properties during the identification of gemstone. Specific gravity of Phlogopite is 5.5 whereas that of Microlite is 5.5.
