Cuprite and Sunstone Chemical Formula
While comparing Cuprite and Sunstone 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 Cuprite and Sunstone chemical formula.

Cuprite and Sunstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cuprite and Sunstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cuprite and Sunstone Optical Properties during the identification of gemstone. Specific gravity of Cuprite is 2.62-2.65 whereas that of Sunstone is 2.62-2.65.
