Chalcedony and Moonstone Chemical Formula
While comparing Chalcedony 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 Chalcedony and Moonstone chemical formula.
- Chemical formula of Chalcedony- SiO2
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
Chalcedony and Moonstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcedony and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcedony and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Chalcedony is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
