Moonstone and Glaucophane Chemical Formula
While comparing Moonstone and Glaucophane 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 Glaucophane chemical formula.
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
- Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2
Moonstone and Glaucophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Glaucophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Glaucophane Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 3-3.15 whereas that of Glaucophane is 3-3.15.
