Chlorite group and Celestine Chemical Formula

While comparing Chlorite group and Celestine 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 Chlorite group and Celestine chemical formula.

  • Chemical formula of Chlorite group- (Mg,Fe)3(Si,Al)4O10(OH)2·(Mg,Fe)3(OH)6
  • Chemical formula of Celestine- SrSO 4Michael O’Donoghue , Gems, Sixth Edition (2006) More from other references

Chlorite group and Celestine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chlorite group and Celestine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorite group and Celestine Optical Properties during the identification of gemstone. Specific gravity of Chlorite group is 3.90-4.00 whereas that of Celestine is 3.90-4.00.
