My girlfriend and I are heading over to Bali in early October, she wants to take a couple of gold bangles and a silver diamond ring over, all needing re-sizing to make them smaller to fit her properly, so we are wondering if anyone knows if firstly it's cheaper to do this over there or here and secondly, with the ring being a diamond one, would it be safe to leave with a jeweller and recieve the same diamonds back, without being swapped with a cheaper version, after the work has been finished, something that could just as easy happen over here as over there I figure, any help or advice would be greatly appreciated. I don't mean to offend anyone by saying this about the diamonds but the ring has a lot of sentimental value and we'd hate for it to be damaged in any way.
