I had two sets of wedding rings first time round. Every day set was specially designed in titanium, engagement ring was a tension set diamond. The wedding ring is lying at the bottom of Leith docks (chucked off the Royal Yacht Britannia, twas a great day and I video'd it), the engagement ring I gave to the lovely man who looked after our room on our recent holiday to Bali (to give to his wife).
I still have the other set, diamond wedding band and bling engagement ring. Not sure what to do with them, I certainly don't want to keep them or have them reset. Thought about selling them and donating the money to charity or donating the rings themselves to charity so they could maybe use them in an auction or something. Be happy to hear ideas
