Specific Gravity - Gemology

Specific Gravity. Specific Gravity (SG), or the relative density of a gem material, is important to gemologists in identifying an unknown specimen, and to jewelers and jewelry lovers in matching the setting size to the gem weight. SG is calculated as the ratio of the density of a given volume of the gem to the same volume of water.

Gemstone Specific Gravity (density) - wikigempedia.com

Density, or specific gravity, is a bulk property of a mate­ rial that is independent of direction and is uniform within a mass of material under ideal circumstances. In actuality, the density of a mineral varies widely, even within a single crystal, due to the presence of impu­ rities, cracks, and bubbles. Density is a useful parameter in gem identification, so the problems in its determina ...
