Specific Gravity

13 12 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.
