Emerald and Coral Chemical Formula
While comparing Emerald and Coral 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 Coral chemical formula.
- Chemical formula of Emerald- Be3Al2SiO6
- Chemical formula of Coral- CaCO 3Ulrich Henn and Claudio C.
Emerald and Coral Specific Gravity
Another important criteria for qualitative analysis of gemstones is Emerald and Coral Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Emerald and Coral Optical Properties during the identification of gemstone. Specific gravity of Emerald is 2.60-2.70 whereas that of Coral is 2.60-2.70.
