Chrysoberyl and Andesine Chemical Formula
While comparing Chrysoberyl 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 Chrysoberyl and Andesine chemical formula.
- Chemical formula of Chrysoberyl- BeAl 2 O 4
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
Chrysoberyl and Andesine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoberyl and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoberyl and Andesine Optical Properties during the identification of gemstone. Specific gravity of Chrysoberyl is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
