Hematite and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Hematite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hematite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Hematite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
