12/13/2016· 2 Specific Gravity of Some Common Gem Minerals; 3 Related topics; Basic. Specific gravity (also known as "relative density") is the ratio between the weight of a stone in air and the weight of an equal volume in water. By convention, the temperature of the water is 4° C and at standard atmosphere because the density of water is greatest under ...

Dry weight divided by loss equals specific gravity: In fact, the specific gravity of barite varies between and 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 is the number of times heavier a gemstone of any volume is than an equal volume of water; in other words, it is the ratio of the density of the gemstone to the density of water. The 16 mineral gemstone groups listed below are highly prized for their beauty, durability, and rarity: Beryl (hardness: Mohs) Beryllium aluminum silicate Specific gravity: Emerald ...

The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference at this point the density of water is at the highest.. Specific gravities SG for common solids and metals can be found in the table below:

The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of If a mineral has a specific gravity of, it is times heavier than water.

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, beryllium has a specific gravity (sg) of (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units.

· 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 = (whereas the density of Diamond = g/cm³). In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes'' Principle.

· 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).

Specific Gravity. Another tool that is available for identifying unknown mineral specimens is specific gravity. A person who studies minerals can measure the specific gravity of a specimen by comparing its weight with the weight of an equal volume of water. In actual practice a mineralogist may use the following procedure: First, weigh the unknown specimen while it is dry. Then, using a ...

Minerals can usually be identified by their specific gravity (SG). Because samples of the same mineral may appear quite different, as these samples of cinnabar show, a quantitative, objective measurement like SG may help confirm their identity. SG might also be used (as Archimedes did) to distinguish pure gold (SG = ) from 14K gold (SG =) or pyrite (SG = ). Some specific gravities ...
