Omphacite and Larvikite Physical Properties

Omphacite and Larvikite Chemical Formula

While comparing Omphacite and Larvikite 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 Larvikite chemical formula.

• Chemical formula of Omphacite- (Ca,Na)(Mg,Fe,Al)Si 2O 6Anthony et al , Handbook of Mineralogy (2001)
• Chemical formula of Larvikite- (Na,Ca)2(Fe2+,Mg)3Si3O10

Omphacite and Larvikite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Omphacite and Larvikite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Omphacite and Larvikite Optical Properties during the identification of gemstone. Specific gravity of Omphacite is 2.59 whereas that of Larvikite is 2.59.
