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