Why do diamonds have these properties ​?

A carbon atom can form four covalent bonds. This lets the carbon atom form many organic compounds (e.g. Diamond).

Diamond has a covalent structure in which:

1) Each carbon atom is joined to four other carbon atoms by covalent bonds.

2) The carbon atoms have a regular lattice arrangement.

3) It doesn't have free electrons

The strong structure, held together by strong covalent bonds, makes diamond very hard.
