While comparing Verdite and Orthoclase 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 Verdite and Orthoclase chemical formula.
Another important criteria for qualitative analysis of gemstones is Verdite and Orthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdite and Orthoclase Optical Properties during the identification of gemstone. Specific gravity of Verdite is 2.54-2.61 whereas that of Orthoclase is 2.54-2.61.
