Montebrasite and Carletonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Montebrasite and Carletonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Carletonite Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 2.45 whereas that of Carletonite is 2.45.
