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