Really? Please realize that moving the metal, that's what sizing means, is not only a problem, but a real problem. The diamonds are set either pressed to the gold with many gold covering the diamonds, or held in place with prongs. The moment you play around with the structure with the ring by sizing the ring up or down, you risk the stones receding sooner or later. Let me clarify that... you may leave the jewelry store using a perfect pave diamond ring, but a few months following the purchase stones might start falling out. There really isn't anything quite as frustrating, than needing to send your ring back to the jeweler again and again, due to loose diamonds. http://www.perfectwedding.ie/
