My husband and I just had our rings cleaned. I also kinda lost a diamond on my wedding band. NO PROBLEM FOR SHANE CO. Part of their lifetime guarantee is replacing lost diamonds and cleaning. We got our rings back a couple days later and they looked just the way they did the first day we bought them. You know how much they charged us? NOTHING!! This is what you buy when you buy any Shane Co. jewelry. Lifetime service and maintenance is included for zero dollars.
