Andesine and Pyrope Chemical Formula
While comparing Andesine and Pyrope 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 Andesine and Pyrope chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Pyrope- Mg 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
Andesine and Pyrope Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Pyrope Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Pyrope Optical Properties during the identification of gemstone. Specific gravity of Andesine is 3.62-3.87 whereas that of Pyrope is 3.62-3.87.
