Moonstone and Omphacite Chemical Formula
While comparing Moonstone and Omphacite 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 Omphacite chemical formula.
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8

Moonstone and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
