Larvikite and Staurolite Physical Properties

Larvikite and Staurolite Chemical Formula

While comparing Larvikite and Staurolite 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 Staurolite chemical formula.

• Chemical formula of Larvikite- (Na,Ca)2(Fe2+,Mg)3Si3O10
• Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.

Larvikite and Staurolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Larvikite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Larvikite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Larvikite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
