DENSITY and SPECIFIC GRAVITY

Diamond, with a specific gravity of 3.4, is a moderately heavy mineral even though it consists only of carbon, an element of low atomic mass. The atoms in diamond are arranged in an exceptionally tight-knit structure. The carbon atoms in graphite occur in a structure that is more open, so graphite has a specific gravity of only 2.3.

Diamond - Wikipedia

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes, with each bound to three nearest neighbors 120 …
