Orthoclase and Star Ruby Specific Gravity
Another important criteria for qualitative analysis of gemstones is Orthoclase and Star Ruby Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Star Ruby Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 3.95-4.10 whereas that of Star Ruby is 3.95-4.10.
