Labradorite and Friedelite Chemical Formula
While comparing Labradorite and Friedelite 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 Friedelite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Friedelite- Mn 8Si 6O 15(OH,Cl) 10Ulrich Henn and Claudio C.
Labradorite and Friedelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Friedelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Friedelite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 3.06-3.19 whereas that of Friedelite is 3.06-3.19.
