Anorthoclase and Anorthite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anorthoclase and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anorthoclase and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Anorthoclase is 2.77 whereas that of Anorthite is 2.77.
