Hi there, I'm just back from JewelleryRepair.ie and wanted to post a quick recommendation for the guys above. I have a white gold engagement and wedding ring and to say they were nearly yellow is an understatement! They are now sparkling up at me as I type this mail :lvs They also were a little big on me and used to twist around and they were able to put little balls inside the rim of both rings and this has stopped it. They had everything done in under an hour and I waited in a coffee shop just opposite them. Parking too and half the price of regular jewellers. Re-reading this I sound like their marketing manager but I often get asked for recommendations from clients so thought this might help you. Kind regards, Amanda
