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

Uvite and Realgar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Uvite and Realgar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Realgar Optical Properties during the identification of gemstone. Specific gravity of Uvite is 3.56 whereas that of Realgar is 3.56.
