08.01.2008· Specific gravity is an important tool in gemstone identification that is useful for the gem buyer as well as the gemologist. A 1-carat stone with higher specific gravity will be smaller than a 1-carat stone with lower specific gravity. So don't be surprised when the sapphire you buy is smaller than your diamond. That's because sapphire has a

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). ). The term "relative density" is often preferred in
