Microlite and Sapphire Specific Gravity

Another important criteria for qualitative analysis of gemstones is Microlite and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Microlite and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Microlite is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
