Actinolite and Iddingsite Physical Properties

Actinolite and Iddingsite Chemical Formula

While comparing Actinolite and Iddingsite 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 Iddingsite chemical formula.

• Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
• Chemical formula of Iddingsite- MgO.Fe2O3.3SiO2•4(H2O)

Actinolite and Iddingsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Actinolite and Iddingsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Actinolite and Iddingsite Optical Properties during the identification of gemstone. Specific gravity of Actinolite is 2.5-2.8 whereas that of Iddingsite is 2.5-2.8.
