How difficult would it be for a jeweler to fix a four-prong setting where the prongs are slightly uneven? This picture illustrates, albeit in an exaggerated manner, the problem with the setting. Is this difficult to fix?
ETA: Sorry about the misshapen prongs. The prongs are actually the same size. The spacing is the issue.
