While comparing Chondrodite and Riebeckite 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 Chondrodite and Riebeckite chemical formula.
Another important criteria for qualitative analysis of gemstones is Chondrodite and Riebeckite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chondrodite and Riebeckite Optical Properties during the identification of gemstone. Specific gravity of Chondrodite is 3.28-3.44 whereas that of Riebeckite is 3.28-3.44.
