David Yurman crossover ring with black onyx and diamonds

Beautiful David Yurman crossover ring with black onyx stone and diamonds on a thin gold band. I’m pretty sure this is a size 7 as that is what I typically buy but this one fits looser than others - maybe due to the thin band. Could be easily resized by a jeweler. Only issue I see is some soap build up but would come off with a professional clean.
