Diopside and Sapphire Physical Properties

Diopside and Sapphire Chemical Formula

While comparing Diopside and Sapphire 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 Sapphire chemical formula.

• Chemical formula of Diopside- CaMgSi₂O₆
• Chemical formula of Sapphire- Al ₂ O ₃

Diopside and Sapphire Specific Gravity

Another important criteria for qualitative analysis of gemstones is Diopside and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diopside and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Diopside is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
