While comparing Goshenite and Spinel 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 Goshenite and Spinel chemical formula.
Another important criteria for qualitative analysis of gemstones is Goshenite and Spinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goshenite and Spinel Optical Properties during the identification of gemstone. Specific gravity of Goshenite is 3.64-3.66 whereas that of Spinel is 3.64-3.66.
