Sapphire and Fuchsite Chemical Formula
While comparing Sapphire and Fuchsite 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 Fuchsite chemical formula.
- Chemical formula of Sapphire- Al 2 O 3
- Chemical formula of Fuchsite- K(Al,Cr) 3Si 3O 10(OH) 2Gemdat.org , Management Team (2012)
Sapphire and Fuchsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
