Crocus cloth doesn't produce a mirror shine, usually because of the way the abrasive is presented to the substrate but rouge on a cotton buff will produce a mirror finish. This is often the final abrasive used to polish jewelry etc. Coe High Buff (zirconium silicate, I believe) can produce as fine or finer finish. ALOX or SiC, in the grits you normally see around the shop are orders of magnitude courser.
