Osmium: Specific Gravity = 2248Ice: Specific Gravity = 09165 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 mistakeSpecific Gravity, also known as SG, is a measurement that determines the density of mineralsTwo minerals may be the same size, but their weight may be very different The specific gravity of a mineral determines how heavy it is by its relative weight to waterSpecific Gravity: Mineral Properties The Mineral andTo determine each minerals specific gravity, a standard to measure each against was needed The standard that was chosen was the weight of water To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of water Weigh the water that was displaced by the mineralHow to Find and Determine the Specific Gravity of a Rock

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)How do I calculate specific gravity? To calculate the specific gravity (SG) of an object, you compare the object's density to the density of water: Because the density of water in g/cm 3 is 10, the SG of an object is will be almost the same as its density in g/cm 3 However, specific gravityCalculating DensityThe most common equation for the specific gravity (SG) of a mineral is this: It's pretty simple to work out: 1 Weigh the mineral in air (literally put in on the scales like normal) 2 Suspend the mineral in water for the second weighing Legend has it that is was Archimedes who discovered that the weight of the mineral in air minus its weightHow to Measure Specific Gravity of Rocks & Is It Important

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 52, meaning 1cm 3 of magnetite will be 52 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 handspecific gravity is: 3758 g/cm3 ÷ 10 g/cm = 758 Densities of minerals Most common minerals in Earth’s crust have specific gravities ranging from 26 to 28 Quartz, for example, has a specific gravity of 265, calcite 272, and the common feldspars from 260 to 275 Among all minerals, densities range widely, from about 15 to almost 23DENSITY and SPECIFIC GRAVITY earth2classSpecific Gravity is a measure of the density of a mineral At times it is such a useful property that it is the only way to distinguish some minerals without laboratory or optical techniques Gold (pictured) can easily be distinguished from "fool's gold" by specific gravity alone, although there are many other waysMINERAL GALLERY SPECIFIC GRAVITY
