Moonstone and Poldervaartite Chemical Formula
While comparing Moonstone and Poldervaartite 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 Poldervaartite chemical formula.
- Chemical formula of Moonstone- Plagioclase Feldspar s: (Na,Ca)Al1-2Si3-2O8 Orthoclase Feldspar : KAlSi3O8
- Chemical formula of Poldervaartite- (Ca,Mn2+ ) 2(SiO 3OH)(OH)Anthony et al , Handbook of Mineralogy (2001)
Moonstone and Poldervaartite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Poldervaartite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Poldervaartite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 2.91 whereas that of Poldervaartite is 2.91.
