Orthoclase and Apophyllite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Apophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Apophyllite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.30-2.50 whereas that of Apophyllite is 2.30-2.50.
