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