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