Orthoclase and Malachite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Malachite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Malachite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 3.25-4.10 whereas that of Malachite is 3.25-4.10.
