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