Variscite and Pyrope Chemical Formula
While comparing Variscite and Pyrope 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 Variscite and Pyrope chemical formula.

- Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
Variscite and Pyrope Specific Gravity
Another important criteria for qualitative analysis of gemstones is Variscite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Variscite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Variscite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
