Emerald and Andesine Chemical Formula
While comparing Emerald and Andesine 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 Andesine chemical formula.
- Chemical formula of Emerald- Be3Al2SiO6
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
Emerald and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Emerald and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Emerald and Andesine Optical Properties during the identification of gemstone. Specific gravity of Emerald is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
