Nuummite and Pyrope Physical Properties

Nuummite and Pyrope Chemical Formula

While comparing Nuummite 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 Nuummite and Pyrope chemical formula.

• Chemical formula of Nuummite- Na(Fe,Mg)7(AlSi7O22)(OH)2
• Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)

Nuummite and Pyrope Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nuummite and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nuummite and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Nuummite is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
