Labradorite and Peridot Chemical Formula
While comparing Labradorite and Peridot 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 Peridot chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Peridot- (Mg,Fe)2SiO4
Labradorite and Peridot Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Peridot Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Peridot Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 1.54-1.55 whereas that of Peridot is 1.54-1.55.
