Gemstone Density: The Definitive Guide at AJS Gems

The density is expressed as a number which indicates how much heavier the gemstone is compared to an equal volume of water. Most gemstone varieties are 2 to 4 times denser than a equal volume of water. But the range is quite wide -- from 8 for cinnabar to 1 for amber. Diamond, at 3.50 to 3.53, falls approximately in the middle.
