Ajoite and Gedrite Chemical Formula
While comparing Ajoite 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 Ajoite and Gedrite chemical formula.
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Ajoite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ajoite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
