While comparing Tsavorite and Afghanite 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 Tsavorite and Afghanite chemical formula.
Another important criteria for qualitative analysis of gemstones is Tsavorite and Afghanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tsavorite and Afghanite Optical Properties during the identification of gemstone. Specific gravity of Tsavorite is 2.55-2.65 whereas that of Afghanite is 2.55-2.65.
