While comparing Brookite and Color change 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 Brookite and Color change garnet chemical formula.
Another important criteria for qualitative analysis of gemstones is Brookite and Color change garnet Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Color change garnet Optical Properties during the identification of gemstone. Specific gravity of Brookite is Not Available whereas that of Color change garnet is Not Available.
