I am getting a three stone diamond setting ring and I was trying to decide between white gold and platinum. I was planning to get platinum and a local jeweler said because the three diamonds are not flush, meaning my center stone will be raised a little higher than the other two diamonds he said I should go with white gold. He said my center diamond will move a lot in platinum and I will not like it. Is there any truth to that? I don't want to have to keep taking my ring in to get tightened all the time and I don't want to lose my diamond either! Please advise!
