Liddicoatite and Rubellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Liddicoatite and Rubellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Liddicoatite and Rubellite Optical Properties during the identification of gemstone. Specific gravity of Liddicoatite is 3.01-3.06 whereas that of Rubellite is 3.01-3.06.
