Pyrope and Riebeckite Physical Properties

Pyrope and Riebeckite Chemical Formula

While comparing Pyrope and Riebeckite 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 Riebeckite chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Riebeckite- Na2Fe2+3Fe3+2Si8O22(OH)2

Pyrope and Riebeckite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Riebeckite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Riebeckite Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 3.28-3.44 whereas that of Riebeckite is 3.28-3.44.
