Danburite and Chromite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Danburite and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Danburite and Chromite Optical Properties during the identification of gemstone. Specific gravity of Danburite is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
