Orthoclase and Emerald Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Emerald Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
