Labradorite and Kornerupine Chemical Formula
While comparing Labradorite and Kornerupine 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 Kornerupine chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Kornerupine- Mg 3Al 6(Si,Al,B) 5O 21(OH)Walter Schumann , Gemstones of the world (2001) More from other references
Labradorite and Kornerupine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Kornerupine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Kornerupine Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 3.25-3.45 whereas that of Kornerupine is 3.25-3.45.
