Vivianite and Orthoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Vivianite and Orthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vivianite and Orthoclase Optical Properties during the identification of gemstone. Specific gravity of Vivianite is 2.54-2.61 whereas that of Orthoclase is 2.54-2.61.
