Within the last two weeks two small diamonds have fallen out of my engagement ring (and been lost). I'm planning to take it into the jewellers we bought it from 10 years ago to see how much it would cost to replace them and check the clasps for the other stones to prevent any others from coming loose. I know it's been a long time but I thought engagement rings were supposed to last forever! I haven't banged it or anything. Should the jeweller replace them even though it's been so long? I'm not sure whether to even ask, advice welcome!
