uzzah! This new ring is milled from a solid slab of copper / niobium Superconductor. I call it Copperhead. The patterning is just spectacular in this material, can't stop looking at it! A big shout-out to @coppercloudsc for the material advising. I'm not first person to work with this superconductor material, not by a longshot.
