Triplite and Lapis lazuli Specific Gravity
Another important criteria for qualitative analysis of gemstones is Triplite and Lapis lazuli Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Triplite and Lapis lazuli Optical Properties during the identification of gemstone. Specific gravity of Triplite is 2.50-3.00 whereas that of Lapis lazuli is 2.50-3.00.
