Girasol and Forsterite Chemical Formula
While comparing Girasol 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 Girasol and Forsterite chemical formula.

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