I designed these rings as a commission piece, but the process was a bit different. I printed them in plastic, and then used a 'lost plastic' casting process, that is similar to the ancient lost wax process but is new due to the availability of 3d printing, see my video on the process here:https://www.youtube.com/watch?v=qYaMhw1PZqg. These rings are sized for a ring size of 11 and 12.5. If you want them in a different size please contact me and I can resize them to whatever size works for you! Please note that the photograph that I have in place (not the rendering) is of the 3d printed, cast rings that I then patinated with liver of sulphur to make them black, and then polished.
