Sapphire and Ajoite Chemical Formula
While comparing Sapphire and Ajoite 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 Sapphire and Ajoite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
Sapphire and Ajoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.96 whereas that of Ajoite is 2.96.
