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

Hyalite and Chiastolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hyalite and Chiastolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Chiastolite Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 3.00-3.15 whereas that of Chiastolite is 3.00-3.15.
