While comparing Poldervaartite and Andesine 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 Poldervaartite and Andesine chemical formula.
Another important criteria for qualitative analysis of gemstones is Poldervaartite and Andesine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Poldervaartite and Andesine Optical Properties during the identification of gemstone. Specific gravity of Poldervaartite is 2.65-2.69 whereas that of Andesine is 2.65-2.69.
