I might be able to save you a lot of time and headache. If you have a Littman Jewelers in your area I would definitely check them out. They sell a bridal diamond ring collection called Say I Do. Also, Littman Jewelers offers a lifetime warranty on the diamonds for around $200.00. If anything happens to the diamonds (lost or damaged) it’s covered. The warranty alone is a huge selling point. The only thing you need to do is have it cleaned (which is free) and inspected every 6 months in order to keep the warranty valid. This diamond ring collection will not break your bank. You can get something really nice for her that’s less than a new Stern Pro. They usually have special financing for 6 months or 1 year at 0% interest. Also, again if anything happens to the diamonds your covered under warranty and not stuck having to shell out another couple thousand for a replacement. She gets the ring she always wanted. You keep your pins and have more money for additional pins. A win win situation.
