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