While comparing Microcline and Microcline 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 Microcline and Microcline chemical formula.
Another important criteria for qualitative analysis of gemstones is Microcline and Microcline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Microcline and Microcline Optical Properties during the identification of gemstone. Specific gravity of Microcline is 2.55-2.63 whereas that of Microcline is 2.55-2.63.
