Moonstone and Labradorite Chemical Formula
While comparing Moonstone and Labradorite 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 Moonstone and Labradorite chemical formula.
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
Moonstone and Labradorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Labradorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Labradorite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 2.69-2.72 whereas that of Labradorite is 2.69-2.72.
