Sg might also be used as archimedes did to distinguish pure gold sg 193 from 14k gold sg 133 or pyrite sg 51 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
Read More >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 waters density equals 1 gram per cubic centimeter at specific conditions then a minerals specific gravity would also correspond to a minerals density as expressed in grams
Read More >The specific gravity for minerals is customarily rounded to two decimal places the best estimate of the true specific gravity of your unknown mineral is the average spg of your samples so sum the sp g of the individual samples in row 4 and divide by the number of samples 5
