This ring was worn by my Ex-Fiance for about 13 months. It is absolutely gorgeous. I have all the official paperwork from the GIA, and will send as many pics as you would like. The only nicks are on the bottom of the platinum ring where the ring would hit a desk (she had a desk job). They are very small and since on the bottom not that obvious. The ring size is 4.5. The total weight of the diamonds are 2.13. The center radiant diamond is 1.34 with two .25 carat princess cut diamonds to each side (color and clarity are even better than main stone). Then there are a total of 28 full cut diamonds wrapped or (paved) around the ring. There are a total of 31 diamonds. If you need to see the paperwork on it I will fax or mail it to you. If you don't like the listed price, please make a reasonable offer. It was valued at $11,000. Any questions please ask. This is a great opportunity to get a gorgeous ring at a beautiful price. It has been kept in a jewelry box, and kept in safe deposit box. I just figured it was finally time to sell it.
