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

Chiastolite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chiastolite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chiastolite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Chiastolite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
