Piemontite and Microlite Chemical Formula
While comparing Piemontite and Microlite 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 Piemontite and Microlite chemical formula.

Piemontite and Microlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Piemontite and Microlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Piemontite and Microlite Optical Properties during the identification of gemstone. Specific gravity of Piemontite is 5.5 whereas that of Microlite is 5.5.
