Superconductor rings are machined from a single section of superconductor cable. Superconductor cable is made up of many highly conductive titanium-niobium alloy rods, which are then insulated by Copper and formed into a large cable. A cross-section wafer of cable is cut at an angle and made into a ring. The resulting band has a beautiful pattern that is formed by the layers of the niobium-titanium alloy and copper crossing through the ring at different points. No two superconductor rings will look the same, as the resulting patterns will vary based on cable and cut.
