Fibrolite and Poldervaartite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fibrolite and Poldervaartite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fibrolite and Poldervaartite Optical Properties during the identification of gemstone. Specific gravity of Fibrolite is 2.91 whereas that of Poldervaartite is 2.91.
