Pyrope and Pearl Physical Properties

Pyrope and Pearl Chemical Formula

While comparing Pyrope and Pearl 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 Pearl chemical formula.

• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
• Chemical formula of Pearl- CaCO3

Pyrope and Pearl Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrope and Pearl Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrope and Pearl Optical Properties during the identification of gemstone. Specific gravity of Pyrope is 2.60-2.85 whereas that of Pearl is 2.60-2.85.
