Lawsonite and Oligoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lawsonite and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lawsonite and Oligoclase Optical Properties during the identification of gemstone. Specific gravity of Lawsonite is 2.62-2.67 whereas that of Oligoclase is 2.62-2.67.
