The electronic structures and the persistent currents of diamond-like graphene rings (DGRs) are investigated within the tight-binding formalism. The calculations show that an armchair DGR is a metallic ring only at selected ring width N = 3m -1 (m is an integer), while a zigzag one appears to be met
