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