Californite and Sillimanite Physical Properties

Californite and Sillimanite Chemical Formula

While comparing Californite and Sillimanite 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 Californite and Sillimanite chemical formula.

• Chemical formula of Californite- Ca 10Mg 2Al 4(SiO 4) 5(Si 2O 7) 2(OH) 4Ulrich Henn and Claudio C.
• Chemical formula of Sillimanite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth Edition (2006)

Californite and Sillimanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Californite and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Californite and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Californite is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
