How does insurance change if I have my engagement ring and wedding band welded together?

My husband insured my engagement ring when he purchased it. Now that I have two rings, I would like to have them welded together. Would this cancel or nullify the insurance on my engagement ring? Would I have to re-insure the rings after I have them welded together?

It's not going to change them at all. YOu might want to ask your agent to note your file, that the two rings have been welded – but it won't affect value, coverage, or anything else.
