Labradorite and Albite Chemical Formula
While comparing Labradorite and Albite 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 Albite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Albite- NaAlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Labradorite and Albite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Albite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Albite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.60-2.65 whereas that of Albite is 2.60-2.65.
