Amazonite and Gedrite Chemical Formula
While comparing Amazonite and Gedrite 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 Amazonite and Gedrite chemical formula.
- Chemical formula of Amazonite- KAlSi3O8
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Amazonite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Amazonite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amazonite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Amazonite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
