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

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