Chrysoprase and Caledonite Chemical Formula
While comparing Chrysoprase 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 Chrysoprase and Caledonite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)
Chrysoprase and Caledonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
