Emerald and Caledonite Chemical Formula
While comparing Emerald 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 Emerald and Caledonite chemical formula.
- Chemical formula of Emerald- Be3Al2SiO6
- Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)
Emerald and Caledonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Emerald and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Emerald and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Emerald is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
