Ajoite and Almandine Chemical Formula
While comparing Ajoite and Almandine 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 Almandine chemical formula.
- Chemical formula of Ajoite- (K,Na)3Cu20Al3Si29O76(OH)16•~8(H2O)
- Chemical formula of Almandine- Fe 3Al 2(SiO 4) 3Arthur Thomas , Gemstones (2009)
Ajoite and Almandine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ajoite and Almandine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ajoite and Almandine Optical Properties during the identification of gemstone. Specific gravity of Ajoite is 3.95-4.30 whereas that of Almandine is 3.95-4.30.
