Resizing would seem like the right thing to do in such a case, but go beyond a limit and it could actually harm the center stone.       Basically, your gemstone has been adjusted to take the exact pressure from the circular shape of the metal band. While jewelry diamonds can take a lot of punishment, other gems could simply split apart from the wrong kind of tension. Sizing Inlay Rings The potential problems with this are obvious: you could crack inlay gems, or knock them loose. Gem breakage from resizing inlay rings is alarmingly common, especially in cases where the procedure fails to account for pressure from the new shape that the band takes, and the need to protect not just the main stone, but also its neighboring gems. However, there are jewelers who are accomplished at rendering even the most challenging tasks in this area. You just have to make sure you go to the right one.
