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