Pyrope and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope Vs Sard during the identification of gemstone. Specific gravity of Pyrope is whereas that of Sard is .
