Achroite and Gaspeite Chemical Formula
While comparing Achroite and Gaspeite 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 Achroite and Gaspeite chemical formula.

Achroite and Gaspeite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Achroite and Gaspeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Achroite and Gaspeite Optical Properties during the identification of gemstone. Specific gravity of Achroite is 3.71 whereas that of Gaspeite is 3.71.
