Dioptase and Boracite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dioptase and Boracite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Boracite Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 2.95-2.96 whereas that of Boracite is 2.95-2.96.
