Uvite and Variscite Chemical Formula
While comparing Uvite 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 Uvite and Variscite chemical formula.

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