Brucite and Caledonite Chemical Formula

While comparing Brucite and Caledonite 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 Brucite and Caledonite chemical formula.

  • Chemical formula of Brucite- Mg(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)
  • Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)

Brucite and Caledonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brucite and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
