Sapphire and Kunzite Chemical Formula
While comparing Sapphire and Kunzite 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 Kunzite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Kunzite- LiAlSi2O6
Sapphire and Kunzite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Kunzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Kunzite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 3.15-3.21 whereas that of Kunzite is 3.15-3.21.
