Specific Gravity - The Gemology Project

Dec 13, 2016  Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). For instance, the SG of Diamond = 3.52 (whereas the density of Diamond = 3.52 g/cm³). In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle.
