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.

Barite
Barite is a heavy white or light-colored mineral composed of barium, sulfur, and oxygen. It is a relatively soft mineral, so that it can be scratched with a copper penny, but not with the fingernail. The crystals are tabular and have three perfect cleavage directions that yield tablet- shaped fragments when crushed.
Specific Gravity of Minerals - Ohio History Central
Dry weight divided by loss equals specific gravity: 4.5. In fact, the specific gravity of barite varies between 4.3 and 4.6. This results in part from impurities that may be present in varying quantities in different specimens of this mineral. Most minerals have variable specific gravities. In some the variation may be as much as 25%.
specific gravity - calculator.org
Calculating Specific Gravity. The following formula is used to calculate the specific gravity of a material. SG = ρ / ρW. Where SG = specific gravity, ρ = density of the material (kg/m 3 ), ρW = density of water ( kg/m 3 ). The reference density of water at 4 o C (39 o F) is used as the reference as these are the conditions of maximum density.
