I brought my favorite turquoise ring to a local jeweler to resize and when I went to pick it up he presented it back to me newly polished and with a nasty vignette of black staining around the stone. Yikes. This was once a pure and even blue stone with a matt finish. I left the ring with him to try and clean up but at this point I’m nervous about what to expect from him. I don’t know for certain but I’m guessing his silver cleaner is responsible for this. You can still see black residue in the silver details. Here’s a photo of the damaged ring and I’ve inset small photos of the ring before this happened for comparison.
Any thoughts or advice from the group are greatly appreciated.
