Seraphinite and Romanchite Physical Properties

Seraphinite and Romanchite Chemical Formula

While comparing Seraphinite and Romanchite 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 Seraphinite and Romanchite chemical formula.

• Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Romanchite- BaAl2Si2O8

Seraphinite and Romanchite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Seraphinite and Romanchite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Seraphinite and Romanchite Optical Properties during the identification of gemstone. Specific gravity of Seraphinite is 4.70-4.74 whereas that of Romanchite is 4.70-4.74.
