While comparing Rhodolite and Girasol 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 Rhodolite and Girasol chemical formula.
Another important criteria for qualitative analysis of gemstones is Rhodolite and Girasol Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Girasol Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 1.98-2.50 whereas that of Girasol is 1.98-2.50.
