Thulite and Chrysoprase Chemical Formula
While comparing Thulite and Chrysoprase 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 Thulite and Chrysoprase chemical formula.
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
Thulite and Chrysoprase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Chrysoprase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Chrysoprase Optical Properties during the identification of gemstone. Specific gravity of Thulite is 2.58-2.64 whereas that of Chrysoprase is 2.58-2.64.
