While comparing Antimony trioxide and Caledonite 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 Antimony trioxide and Caledonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Antimony trioxide and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Antimony trioxide and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Antimony trioxide is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
