While comparing Nuummite and Marialite 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 Nuummite and Marialite chemical formula.
Another important criteria for qualitative analysis of gemstones is Nuummite and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nuummite and Marialite Optical Properties during the identification of gemstone. Specific gravity of Nuummite is 2.50 whereas that of Marialite is 2.50.
