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