Density orthopyroxene
WebJan 8, 2008 · Specific Gravity Chart. Specific gravity is a way to express the relative density of a gemstone. It is measured as the ratio of the density of the gemstone to the density of water. It is expressed as a number that indicates how much heavier the gemstone is compared to an equal volume of water. Scientifically, specific gravity is defined as a ...
