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