Diamond possess covalent bonds. Diamond is very hard because it consists of very small atoms (carbon) that are tightly packed together and linked via covalent bonds. It is the combination of very tight packing and very tight linking that results in diamond being so hard. Covalent bonding is present in other molecules also, but the strength of the molecule depends on other factors also.
