SuperConductor Flat Ring in 12mm Width Etched with Titanium Liner

A SuperConductor ring in a 12mm width, but the copper has been eaten away from the surface with acid. This leaves the titanium/niobium alloy filaments standing higher. The 12mm width might be considered very wide. The etch finish has more 3D texture than a polished finish, so will feel more bumpy on the skin on the outside of the ring. The inside of the ring has a polished titanium sleeve for comfort. The filaments are polished out so are relatively smooth. They can have a different finish if you prefer. An Angled Brush finish for example would be possible on the filaments. Because this ring has the titanium liner, engraving is possible.
