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