Specific Gravity - The Gemology Project

Dec 13, 2016· 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 these conditions.

Relative density - Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...

Specific Gravity: Mineral Properties - The Mineral and ...

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 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.

Specific Gravity | Mineralogy4Kids

Specific gravity is the "heaviness" of a mineral. It is defined as a number that expresses the ratio between the weight of a mineral and the weight of an equal volume of water. Water has a specific gravity …

University of Minnesota's Mineral Pages: Calcite

A complex pattern of electrons between the two forms of iron is the source of its magnetic nature. Although other metallic minerals may mimic magnetite's color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence.

Mineral Oil Technical Specifications

Ideal Oil Properties The ideal oil would have a specific gravity in the upper portion (> .83) of the range specified under "required properties" and a viscosity between 12 cST at 40 o C (70 SUS at 100 o F) and 18 cSt at 40 o C (100 SUS at 100 o F). For oils with the same specific gravity, we …

Mineral - Hardness | Britannica

Specific gravity. Specific gravity (G) is defined as the ratio between the weight of a substance and the weight of an equal volume of water at 4 °C (39 °F). Thus a mineral with a specific gravity of 2 weighs twice as much as the same volume of water.Since it is a ratio, specific gravity has no units.

specific gravity | Formula, Units, & Equation | Britannica

Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per …

Donald B Peck - Determining the Specific Gravity of a Mineral

Osmium has the highest Specific Gravity among minerals approved by the IMA, ice has the lowest. The Specific Gravity as a property of minerals is often overlooked by amateur collectors, probably because it is considered to be too difficult. . . and that is a mistake. It is one of the most definitive properties of a mineral.

Mica - Wikipedia

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage.All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.

About Specific Gravity

Specific Gravity = Weight of Mineral (in Grams) _____ Volume of Mineral (in Cubic Centimeters) Why measure the specific gravity of a mineral? Because specific gravity is one of the most important, constant, and quantifiable properties of a gem or mineral, and in your effort to identify an unknown stone, the specific gravity, if known, can ...

Conversion Factors and the Specific Gravity of Minerals ...

SG might also be used (as Archimedes did) to distinguish pure gold (SG = 19.3) from 14K gold (SG =13.3) or pyrite (SG = 5.1). Some specific gravities of minerals are shown below. Online mineral vendors sell equipment for determining specific gravity, but it is simple to do in the lab. Specific gravity is related to density, but it is unitless.

MINERAL GALLERY - SPECIFIC GRAVITY

Specific gravity is a unitless measure, because it is derived from the density of the mineral divided by the density of water and thus all units cancel. However, since water's density equals 1 gram per cubic centimeter (at specific conditions), then a mineral's specific gravity would also correspond to a mineral's density as expressed in grams ...

Specific gravity - University of Auckland

Specific gravity Definition. A mineral's specific gravity is the ratio of its mass to the mass of an equal volume of water. For example, magnetite has a specific gravity value of 5.2, meaning 1cm 3 of magnetite will be 5.2 times as heavy as 1cm 3 of water. Test. Although this property can be precisely measured, it is often tested by simply hefting the specimen in the hand.

Mineral - Wikipedia

Among most minerals, this property is not diagnostic. Rock forming minerals – typically silicates or occasionally carbonates – have a specific gravity of 2.5–3.5. High specific gravity is a diagnostic property of a mineral. A variation in chemistry (and consequently, mineral class) correlates to a change in specific gravity.
