Labradorite and Antigorite Chemical Formula
While comparing Labradorite and Antigorite 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 Antigorite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Antigorite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
Labradorite and Antigorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
