Allanite and Seraphinite Physical Properties

Allanite and Seraphinite Chemical Formula

While comparing Allanite and Seraphinite 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 Allanite and Seraphinite chemical formula.

• Chemical formula of Allanite- Ca(Ce,La,Y,Ca)Al2(Fe,Al)Si3O12(OH)
• Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)

Allanite and Seraphinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Allanite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Allanite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Allanite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
