While comparing Variscite and Clinohedrite 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 Variscite and Clinohedrite chemical formula.
Another important criteria for qualitative analysis of gemstones is Variscite and Clinohedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Clinohedrite Optical Properties during the identification of gemstone. Specific gravity of Variscite is 3.28-3.335 whereas that of Clinohedrite is 3.28-3.335.
