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

Hyalite and Cuprite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hyalite and Cuprite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Cuprite Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 5.85-6.15 whereas that of Cuprite is 5.85-6.15.
