While comparing Friedelite and Beudantite 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 Friedelite and Beudantite chemical formula.
Another important criteria for qualitative analysis of gemstones is Friedelite and Beudantite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Friedelite and Beudantite Optical Properties during the identification of gemstone. Specific gravity of Friedelite is 4.48 whereas that of Beudantite is 4.48.
