Chlorite group and Pyrite Physical Properties

Chlorite group and Pyrite Chemical Formula

While comparing Chlorite group and Pyrite 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 Pyrite chemical formula.

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

Chlorite group and Pyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chlorite group and Pyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorite group and Pyrite Optical Properties during the identification of gemstone. Specific gravity of Chlorite group is 5.00-5.20 whereas that of Pyrite is 5.00-5.20.
