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