While comparing Abalone and Forsterite 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 Abalone and Forsterite chemical formula.
Another important criteria for qualitative analysis of gemstones is Abalone and Forsterite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Abalone and Forsterite Optical Properties during the identification of gemstone. Specific gravity of Abalone is 3.23-3.26 whereas that of Forsterite is 3.23-3.26.
