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