While comparing Sulfur and Larimar 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 Sulfur and Larimar chemical formula.
Another important criteria for qualitative analysis of gemstones is Sulfur and Larimar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sulfur and Larimar Optical Properties during the identification of gemstone. Specific gravity of Sulfur is 2.74-2.90 whereas that of Larimar is 2.74-2.90.
