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