Oligoclase and Ludlamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Oligoclase and Ludlamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Ludlamite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 3.1-3.2 whereas that of Ludlamite is 3.1-3.2.
