Copper and Sapphire Physical Properties

Copper and Sapphire Chemical Formula

While comparing Copper 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 Copper and Sapphire chemical formula.

• Chemical formula of Copper- Cu
• Chemical formula of Sapphire- Al ₂ O ₃

Copper and Sapphire Specific Gravity

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