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