Larvikite and Norbergite Physical Properties

Larvikite and Norbergite Chemical Formula

While comparing Larvikite and Norbergite 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 Larvikite and Norbergite chemical formula.

• Chemical formula of Larvikite- (Na,Ca)2(Fe2+,Mg)3Si3O10
• Chemical formula of Norbergite- Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001)

Larvikite and Norbergite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Larvikite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Larvikite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Larvikite is 3.177 whereas that of Norbergite is 3.177.
