Moldavite and Pumpellyite Chemical Formula
While comparing Moldavite and Pumpellyite 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 Moldavite and Pumpellyite chemical formula.
- Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
- Chemical formula of Pumpellyite- Ca 2(Mg,Fe,Mn,Al) 2(SiO 4)(Si 2O 7)(OH) 2 · H 2OUlrich Henn and Claudio C.
Moldavite and Pumpellyite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Pumpellyite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Pumpellyite Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 3.20-3.30 whereas that of Pumpellyite is 3.20-3.30.
