Linarite and Romanchite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Linarite and Romanchite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Linarite and Romanchite Optical Properties during the identification of gemstone. Specific gravity of Linarite is 4.70-4.74 whereas that of Romanchite is 4.70-4.74.
