While comparing Peridot and Amblygonite 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 Peridot and Amblygonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Peridot and Amblygonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Peridot and Amblygonite Optical Properties during the identification of gemstone. Specific gravity of Peridot is 2.98-3.10 whereas that of Amblygonite is 2.98-3.10.
