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