Diopside and Orthoclase Chemical Formula

While comparing Diopside 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 Diopside and Orthoclase chemical formula.

Diopside and Orthoclase Specific Gravity

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