If you have a ring that needs sizing, redesigning, repaired or an arthritic shank added so you can wear it.
Out of all of your jewelry, rings will get the most wear and should be checked out on a regular bases. A bracelet or wrist watch would be the next jewelry items to receive the most wear and tear. Earrings should also have the clips and backs checked to prevent them from falling off during the day. A necklace should have the clasps checked from time to time as well.
