Chiastolite and Hibschite Physical Properties

Chiastolite and Hibschite Chemical Formula

While comparing Chiastolite and Hibschite 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 Chiastolite and Hibschite chemical formula.

• Chemical formula of Chiastolite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth edition (2006)
• Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)

Chiastolite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chiastolite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chiastolite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Chiastolite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
