Ulexite and Hauyne Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ulexite and Hauyne Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ulexite and Hauyne Optical Properties during the identification of gemstone. Specific gravity of Ulexite is 2.4-2.5 whereas that of Hauyne is 2.4-2.5.
