Spodumene and Pyrope Specific Gravity

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