Ludlamite and Hydrophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ludlamite and Hydrophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ludlamite and Hydrophane Optical Properties during the identification of gemstone. Specific gravity of Ludlamite is 1.98-2.50 whereas that of Hydrophane is 1.98-2.50.
