Andesine and Rock Crystal Chemical Formula
While comparing Andesine and Rock Crystal 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 Rock Crystal chemical formula.
- Chemical formula of Andesine- (Na,Ca)Al1-2Si3-2O8
- Chemical formula of Rock Crystal- SiO 2Walter Schumann , Gemstones of the world (2001)
Andesine and Rock Crystal Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andesine and Rock Crystal Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andesine and Rock Crystal Optical Properties during the identification of gemstone. Specific gravity of Andesine is 2.65 whereas that of Rock Crystal is 2.65.
