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 orbital hybrids and the atoms form in planes, with each bound to three nearest neighbors 120 degrees apart. … Diamond is the hardest natural material in the world. However, it's also brittle. Scientifically speaking, hardness measures the ability to resist scratching, nothing more. A gemstone's overall wearability grade takes hardness into account.
