While comparing Gahnospinel and Chrysoprase 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 Gahnospinel and Chrysoprase chemical formula.
Another important criteria for qualitative analysis of gemstones is Gahnospinel and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnospinel and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Gahnospinel is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
