Monazite and Hessonite Physical Properties

Monazite and Hessonite Chemical Formula

While comparing Monazite and Hessonite 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 Monazite and Hessonite chemical formula.

• Chemical formula of Monazite- (Ce,La,Nd,Th)PO 4Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Hessonite- Ca3Al2(SiO4)3

Monazite and Hessonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Monazite and Hessonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Monazite and Hessonite Optical Properties during the identification of gemstone. Specific gravity of Monazite is 3.55-3.73 whereas that of Hessonite is 3.55-3.73.
