Actinolite and Londonite Chemical Formula
While comparing Actinolite and Londonite 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 Actinolite and Londonite chemical formula.

Actinolite and Londonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Actinolite and Londonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Actinolite and Londonite Optical Properties during the identification of gemstone. Specific gravity of Actinolite is 3.34 whereas that of Londonite is 3.34.
