Prehnite and Fluorite Chemical Formula
While comparing Prehnite and Fluorite 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 Prehnite and Fluorite chemical formula.
- Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
- Chemical formula of Fluorite- CaF2
Prehnite and Fluorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
