Nepheline and Xenotime Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepheline and Xenotime Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Xenotime Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 4.30-5.10 whereas that of Xenotime is 4.30-5.10.
