While comparing Rose Quartz and Hypersthene 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 Rose Quartz and Hypersthene chemical formula.
Another important criteria for qualitative analysis of gemstones is Rose Quartz and Hypersthene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rose Quartz and Hypersthene Optical Properties during the identification of gemstone. Specific gravity of Rose Quartz is 3.45-3.55 whereas that of Hypersthene is 3.45-3.55.
