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