I have an engagement ring that my dh and I designed and took to a jeweller to make - long story short but it was nothing like what either of us expected. We ended up taking it to another jeweller some months later as it still hadn't grown on us, and he did a great job of fixing it so that it resembled what we had first hoped for. It was still not quite right, be he did a great job of amending it without needing to remake it, saving us loads.
We have now been married 4.5 years and I've never been totally happy with the set. I've often said I want to modify/remake/buy new ones but it seems funny as the current ones will be in years worth of photos. Plus 2 kids and buying a house later, it always seemed like it wasn't worth the money. My dh has agreed that we could change them for our 5th wedding anniversary, but I'm not sure what to do. I think altering may well cost more than buying again once you add manufacturing costs to materials. But I wouldn't know what to do with the old ones and might feel a little sad.
Have you altered the look or style of your rings after the fact? What did you do with the old ones or could you use the metal? Any tips or ideas?
