While comparing Shungite and Larvikite 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 Shungite and Larvikite chemical formula.
Another important criteria for qualitative analysis of gemstones is Shungite and Larvikite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shungite and Larvikite Optical Properties during the identification of gemstone. Specific gravity of Shungite is 2.59 whereas that of Larvikite is 2.59.
