Lazulite and Goldstone Specific Gravity

Another important criteria for qualitative analysis of gemstones is Lazulite and Goldstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazulite and Goldstone Optical Properties during the identification of gemstone. Specific gravity of Lazulite is 2.50-2.80 whereas that of Goldstone is 2.50-2.80.
