Labradorite and Scolecite Chemical Formula
While comparing Labradorite and Scolecite 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 Labradorite and Scolecite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Scolecite- CaAl 2Si 3O 10 · 3H 2OUlrich Henn and Claudio C.
Labradorite and Scolecite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Scolecite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Scolecite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.20-2.23 whereas that of Scolecite is 2.20-2.23.
