Sapphire and Stichtite Chemical Formula
While comparing Sapphire and Stichtite 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 Stichtite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Stichtite- Mg 6Cr 2(CO 3)(OH) 16 · 4H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Sapphire and Stichtite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Stichtite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Stichtite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.11-2.20 whereas that of Stichtite is 2.11-2.20.
