WebMost gemstones are harder than quartz (Mohs scale greater than 7) and cannot be scratched by the blade of a knife. For example, diamond has a specific gravity of 3.52 and a cubic zirconia, which looks very similar, has a specific gravity of 5.80. This means that cubic zirconium is heavier than diamond.

To judge heft, bounce the stone in the palm of your hand and ask yourself if it feels as heavy as you would expect for its size or if it feels heavier or unusually light.
Gemologists usually measure specific gravity with heavy liquids. They prepare a liquid, such as a mixture of bromoform and toluene, to have a particular density value. When an unknown material is dropped into the liquid, it may sink, float, or remain suspended in place. If the material sinks, it has greater … See more In case you forgot your high school science, density refers to how much mass something has per unit of volume. Or, think of density as the "compactness" of an item. For example, vegetable oil is less dense than vinegar. … See more The density of a compound is a function of several factors, including chemical composition and crystal structure. For example, consider diamond and graphite. Both are polymorphouscrystalline forms of the element carbon … See more The presence of impurities within crystals poses a major problem for all gemstone density measurements. These impurities hardly ever have the same specific gravity as the host material. … See more
