so my girlfriend has her grandmother''s antique diamond ring. There''s a loose prong on a side stone, so she takes it to a jeweler to have it fixed. They send it out, and it comes back with yellow gold prongs (the ring is white gold). They fix that for free, no problem. When the other side gets loose, she takes it back assuming that she better make sure both sides are uniform and the work matches. When we get it back, there''s clearly something wrong. The side stone is cloudy and yellowish. We go to another jeweler and he tells us it may have been burned. We return to the original place and the jeweler has the nerve to tell me that diamonds can''t be burned, in fact, that''s how they are created (intense heat). She also tells us that its fine, thats the same stone we gave her. I agree it probably is the same stone, nobody''s going to switch out a 70 stone, i just don''t think it''s in the same condition we left it in. We get our money back, but the stone will have to be polished, hopefully not replaced. What really concerns me though is the ring itself. It looks uneven. The side with the burnt stone, underneath the diamond the metal looks melted and distorted. On the other side there are two very small holes that you could clearly look through. On the burnt side, the holes are almost shut. What do you think happened here? Did the jeweler leave his torch on the whole damn thing while he went to look for the boracic acid he forgot to apply?
