Caledonite and Euclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Caledonite and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Caledonite and Euclase Optical Properties during the identification of gemstone. Specific gravity of Caledonite is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
