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

Caledonite and Hyalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Caledonite and Hyalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Caledonite and Hyalite Optical Properties during the identification of gemstone. Specific gravity of Caledonite is Not Available whereas that of Hyalite is Not Available.
