Shigaite and Dioptase Chemical Formula
While comparing Shigaite and Dioptase 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 Shigaite and Dioptase chemical formula.

Shigaite and Dioptase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Shigaite and Dioptase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shigaite and Dioptase Optical Properties during the identification of gemstone. Specific gravity of Shigaite is 3.25-3.35 whereas that of Dioptase is 3.25-3.35.
