Labradorite and Carletonite Chemical Formula
While comparing Labradorite 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 Labradorite and Carletonite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Carletonite- KNa 4Ca 4Si 8O 18(CO 3) 4(OH,F) · H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Labradorite and Carletonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Carletonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Carletonite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.45 whereas that of Carletonite is 2.45.
