Labradorite and Moonstone Chemical Formula
While comparing Labradorite and Moonstone 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 Moonstone chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
Labradorite and Moonstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
