Prase and Agrellite Physical Properties

Prase and Agrellite Chemical Formula

While comparing Prase and Agrellite 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 Prase and Agrellite chemical formula.

• Chemical formula of Prase- SiO 2Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Agrellite- NaCa2Si4O10F

Prase and Agrellite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Prase and Agrellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prase and Agrellite Optical Properties during the identification of gemstone. Specific gravity of Prase is 2.88 whereas that of Agrellite is 2.88.
