Finger Ring

Two differnt concepts of a very simple FINGER RING with the possibility of a continious variation of the inner diameter, within narrow bounds. The nominal inner diameter of the ring is 18.8 mm or defined as a ring size of "59". The radii to "break" sharp edges are 0.3 mm. What version do you prefer? Is it the version in silver, for an easier manufacturing or the version in gold, for a better fit on the finger? The models are available as STEP files (.stp) and STL files (.stl).
