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

Actinolite and Childrenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Actinolite and Childrenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Actinolite and Childrenite Optical Properties during the identification of gemstone. Specific gravity of Actinolite is 3.06-3.25 whereas that of Childrenite is 3.06-3.25.
