Kornerupine and Piemontite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kornerupine and Piemontite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kornerupine and Piemontite Optical Properties during the identification of gemstone. Specific gravity of Kornerupine is Not Available whereas that of Piemontite is Not Available.
