Topaz and Carletonite Chemical Formula
While comparing Topaz and Carletonite 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 Topaz and Carletonite chemical formula.
- Chemical formula of Topaz- Al2SiO4(F,OH)2
- Chemical formula of Carletonite- KNa 4Ca 4Si 8O 18(CO 3) 4(OH,F) · H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Topaz and Carletonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Carletonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Carletonite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.45 whereas that of Carletonite is 2.45.
