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

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