Jacobsite and Diaspore Chemical Formula

While comparing Jacobsite and Diaspore 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 Diaspore chemical formula.

  • Chemical formula of Jacobsite- (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001)
  • Chemical formula of Diaspore- AlO(OH)Walter Schumann , Gemstones of the world (2001) More from other references

Jacobsite and Diaspore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jacobsite and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jacobsite and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Jacobsite is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
