While comparing Grossular and Binghamite 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 Grossular and Binghamite chemical formula.
Another important criteria for qualitative analysis of gemstones is Grossular and Binghamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Grossular and Binghamite Optical Properties during the identification of gemstone. Specific gravity of Grossular is 2.55-2.70 whereas that of Binghamite is 2.55-2.70.
