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

Sard and Uvite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sard and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sard and Uvite Optical Properties during the identification of gemstone. Specific gravity of Sard is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
