Jacobsite and Gypsum Physical Properties

Jacobsite and Gypsum Chemical Formula

While comparing Jacobsite and Gypsum 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 Gypsum chemical formula.

• Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Gypsum- CaSO 4 -2(H 2O)Arthur Thomas , Gemstones (2009)

Jacobsite and Gypsum Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jacobsite and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
