I am looking at a ring for my wife, it has three euro cut diamonds and the girdle sides are rough not polished. My wife loves the ring but I''m concerned about the quality and/or age of the rocks. Does anyone have knowledge for this? there is a gemologist report with the ring which of course is favorable and does not mention the sides being rough. Does this matter with older stones? I''m not knowledgeable on old miner or euro cuts.
