Liddicoatite and Sellaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Liddicoatite and Sellaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Liddicoatite and Sellaite Optical Properties during the identification of gemstone. Specific gravity of Liddicoatite is 3.14-3.16 whereas that of Sellaite is 3.14-3.16.
