Copper and Ruby Chemical Formula
While comparing Copper and Ruby 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 Ruby chemical formula.
- Chemical formula of Copper- Cu
- Chemical formula of Ruby- Al 2 O 3
Copper and Ruby Specific Gravity
Another important criteria for qualitative analysis of gemstones is Copper and Ruby Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Copper and Ruby Optical Properties during the identification of gemstone. Specific gravity of Copper is 3.97-4.05 whereas that of Ruby is 3.97-4.05.
