Lawsonite and Larimar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lawsonite and Larimar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lawsonite and Larimar Optical Properties during the identification of gemstone. Specific gravity of Lawsonite is 2.74-2.90 whereas that of Larimar is 2.74-2.90.
