Topaz and Copper Specific Gravity

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