Elbaite and Hematite Chemical Formula
While comparing Elbaite and Hematite 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 Elbaite and Hematite chemical formula.

Elbaite and Hematite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Elbaite and Hematite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Elbaite and Hematite Optical Properties during the identification of gemstone. Specific gravity of Elbaite is 5.00-5.30 whereas that of Hematite is 5.00-5.30.
