Rock Crystal and Orthoclase Chemical Formula
While comparing Rock Crystal 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 Rock Crystal and Orthoclase chemical formula.

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