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