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

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