While comparing Almandine and Cavansite 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 Almandine and Cavansite chemical formula.
Another important criteria for qualitative analysis of gemstones is Almandine and Cavansite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Almandine and Cavansite Optical Properties during the identification of gemstone. Specific gravity of Almandine is 2.25-2.33 whereas that of Cavansite is 2.25-2.33.
