While comparing Rhodolite and Heliodor 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 Heliodor chemical formula.
Another important criteria for qualitative analysis of gemstones is Rhodolite and Heliodor Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Heliodor Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is Not Available whereas that of Heliodor is Not Available.
