Brookite and Copper Chemical Formula
While comparing Brookite and Copper 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 Copper chemical formula.

Brookite and Copper Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brookite and Copper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brookite and Copper Optical Properties during the identification of gemstone. Specific gravity of Brookite is Not Available whereas that of Copper is Not Available.
