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