While comparing Carletonite and Topaz 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 Carletonite and Topaz chemical formula.
Another important criteria for qualitative analysis of gemstones is Carletonite and Topaz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Carletonite and Topaz Optical Properties during the identification of gemstone. Specific gravity of Carletonite is 3.49-3.57 whereas that of Topaz is 3.49-3.57.
