Esperite and Ajoite Chemical Formula
While comparing Esperite and Ajoite 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 Esperite and Ajoite chemical formula.
- Chemical formula of Esperite- PbCa 3Zn 4(SiO 4) 4Anthony et al , Handbook of mineralogy (2001)

Esperite and Ajoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Esperite and Ajoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Ajoite Optical Properties during the identification of gemstone. Specific gravity of Esperite is 2.96 whereas that of Ajoite is 2.96.
