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