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