While comparing Plumbogummite and Cristinite 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 Plumbogummite and Cristinite chemical formula.
Another important criteria for qualitative analysis of gemstones is Plumbogummite and Cristinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Plumbogummite and Cristinite Optical Properties during the identification of gemstone. Specific gravity of Plumbogummite is 2.6-3.6 whereas that of Cristinite is 2.6-3.6.
