While comparing Larimar and Bronzite 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 Larimar and Bronzite chemical formula.
Another important criteria for qualitative analysis of gemstones is Larimar and Bronzite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Larimar and Bronzite Optical Properties during the identification of gemstone. Specific gravity of Larimar is 3.35 whereas that of Bronzite is 3.35.
