While comparing Californite and Rosasite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Californite and Rosasite chemical formula.
Another important criteria for qualitative analysis of gemstones is Californite and Rosasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Californite and Rosasite Optical Properties during the identification of gemstone. Specific gravity of Californite is 4-4.2 whereas that of Rosasite is 4-4.2.
