Amber and Prehnite Chemical Formula
While comparing Amber and Prehnite 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 Amber and Prehnite chemical formula.
- Chemical formula of Amber- [C,H,O]
- Chemical formula of Prehnite- Ca2Al2Si3O12(OH)
Amber and Prehnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Amber and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amber and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Amber is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
