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