Hauyne and Petalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hauyne and Petalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hauyne and Petalite Optical Properties during the identification of gemstone. Specific gravity of Hauyne is 2.40 whereas that of Petalite is 2.40.
