While comparing Andean Opal and Chrysotile 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 Andean Opal and Chrysotile chemical formula.
Another important criteria for qualitative analysis of gemstones is Andean Opal and Chrysotile Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andean Opal and Chrysotile Optical Properties during the identification of gemstone. Specific gravity of Andean Opal is 2.51-2.63 whereas that of Chrysotile is 2.51-2.63.
