While comparing Hessonite Garnet and Variscite 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 Hessonite Garnet and Variscite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hessonite Garnet and Variscite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hessonite Garnet and Variscite Optical Properties during the identification of gemstone. Specific gravity of Hessonite Garnet is 2.42-2.58 whereas that of Variscite is 2.42-2.58.
