What is the difference in electronegativity between chemical bonds in diamond(c)? are these bonds ionic or covalent?

Diamond have C-C bonds, so we do not expect difference in electronegativity since only are C atoms. In diamond the bonds are covalent as is expected for bonds between atoms with small difference in electronegativity (<1.7).
