Chiastolite and Prehnite Chemical Formula
While comparing Chiastolite 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 Chiastolite and Prehnite chemical formula.

Chiastolite and Prehnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chiastolite and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chiastolite and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Chiastolite is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
