Omphacite and Pleonast Physical Properties

Omphacite and Pleonast Chemical Formula

While comparing Omphacite and Pleonast 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 Omphacite and Pleonast chemical formula.

• Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
• Chemical formula of Pleonast- MgAl2O4

Omphacite and Pleonast Specific Gravity

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