Langbeinite and Pyrite Specific Gravity

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