Labradorite and Actinolite Chemical Formula
While comparing Labradorite and Actinolite 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 Actinolite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Labradorite and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 3.00 whereas that of Actinolite is 3.00.
