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.

These are andradite, grossular, and uvarovite, the slightly softer, typically green garnets with a lower specific gravity. Two calcium garnets are highly regarded in the gem trade; they are tsavorite (a bright green grossular) and demantoid (a goldengreen andradite). Garnet is a common mineral in skarns. Skarns are metamorphic rocks that have

A generalization is that minerals with metallic or adamantine lustre tend to have higher specific gravities than those having a nonmetallic to dull lustre. For example, hematite, Fe 2 O 3, has a specific gravity of 5.26 while galena, PbS, has a specific gravity of 7.27.6, which is a result of their high iron and lead content, respectively.

Definition of specific gravity Mines, Minerals and More

Definition of specific gravity. i. The ratio between the weight of a unit volume of a substance and that of some other standard substance, under standard conditions of temperature and pressure. For solids and liquids, the specific gravity is based upon water as the standard. The true specific gravity of a body is based on the volume of solid

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%.

Jan 23, 2020· The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
