While comparing Caledonite and Chrome-Chalcedony 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 Chrome-Chalcedony chemical formula.
Another important criteria for qualitative analysis of gemstones is Caledonite and Chrome-Chalcedony Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Caledonite and Chrome-Chalcedony Optical Properties during the identification of gemstone. Specific gravity of Caledonite is 2.55-2.70 whereas that of Chrome-Chalcedony is 2.55-2.70.
