Rhodochrosite and Ulexite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodochrosite and Ulexite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodochrosite and Ulexite Optical Properties during the identification of gemstone. Specific gravity of Rhodochrosite is 1.65-1.99 whereas that of Ulexite is 1.65-1.99.
