Ludlamite and Pleonaste Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ludlamite and Pleonaste Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ludlamite and Pleonaste Optical Properties during the identification of gemstone. Specific gravity of Ludlamite is 3.80 whereas that of Pleonaste is 3.80.
