Update:
A little behind on this project, but getting around to making some changes based on the initial prototypes. The geometry looks good, I plan to focus on making the overall form slimmer and more elegant. The fit is also a little tight so I will open it up some, but the final silver ring will be somewhat flexible doe to the malleability of the metal.
You can see mock-ups here of the integration with a Mexican fire opal. I will work with the digital geometry to mold some of the apertures to fit the round cut gems so that they can be fixed into the final design as a vibrant accent.
