  • Diamond is harder than graphite because of pure carbon, and the atomic bonding of the atoms. Diamond is the hardest substance because of its extremely strong bonding, but there is one direction where the bonds are not as strong, and a diamond can be cleaved with impact along this direction. A diamond cutter considers direction, and as a result, cleavage damage is uncommon in well-cut gem diamonds.

    The structure of a diamond is similar to many pentagons connected together, with each pentagon sharing a side or a point with another pentagon. All of the points are connected in some way. The structure of graphite is very loose, with its bonds forming layers. There will be one sheet of elements bonded together, but another sheet of elements bonded together will lie on top of that, with very weak bonds holding those sheets together.
