While comparing Liddicoatite and Garnet 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 Liddicoatite and Garnet chemical formula.
Another important criteria for qualitative analysis of gemstones is Liddicoatite and Garnet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Liddicoatite and Garnet Optical Properties during the identification of gemstone. Specific gravity of Liddicoatite is 3.55-4.33 whereas that of Garnet is 3.55-4.33.
