Pyrope and Moldavite Chemical Formula
While comparing Pyrope and Moldavite 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 Pyrope and Moldavite chemical formula.
- Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
- Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
Pyrope and Moldavite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pyrope and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
