Gemstone Specific Gravity Chart

Density, or Specific Gravity Chart, is a property that is bulk of material. Specific Gravity is the ratio expressing the extra weight of a mineral when compared with compared to an volume that is equal of at 4° C. So, a certain gravity of 3 implies that, at 4° C, one cubic centimeter regarding the material weighs 3 times just as much as one cubic centimeter of water.
Density is a measurement that is useful gem identification. However, the density of a mineral that is particular vary greatly, even within just one crystal, as a result of the presence of impurities, cracks or bubbles. The density of a mineral may be impacted by several factors, including chemical composition and structure that is crystal. As an example, Diamond and graphite are both crystalline forms of this element carbon. Diamond has a density of 3.5 due to the fact carbon atoms are tightly packed together when you look at the structure. Graphite having said that, has a looser, more structure that is open has a density of only 2.2.
