Jacobsite and Chiastolite Physical Properties

Jacobsite and Chiastolite Chemical Formula

While comparing Jacobsite and Chiastolite 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 Jacobsite and Chiastolite chemical formula.

• Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Chiastolite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth edition (2006)

Jacobsite and Chiastolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jacobsite and Chiastolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Chiastolite Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 3.00-3.15 whereas that of Chiastolite is 3.00-3.15.
