You can get this ring resized and/or polished at Tiffany. Both services should be free of charge since you will have all of the paperwork. Do not size it at a local jeweler; it loses value if not sized at T&Co. I have a copy of the original receipt and an insurance valuation report; therefore, you will be able to get a current valuation report registered in your name. Tiffany has become stricter with providing their valuation reports. If you are not the original owner and only have the diamond certificate, but not the original receipt or valuation report (they want a name), they will not issue you the new insurance valuation report even if you request to purchase it from them. I'm selling because I recently upgraded to a slightly larger Lucida ring. This is a high quality ring in excellent condition. This ring looks great with several T&Co. weddings bands including the plain 2mm Lucida, plain 3mm Lucida, diamond Lucida (half or full eternity), and the 2mm channel-set diamond band (half or full eternity). Please let me know if you would like to see more pictures, as I do have pictures with a couple of bands. According to Tiffany it is reminiscent of the Asscher and antique cushion cuts. Termed a "modern classic" by Tiffany, the shape is a square mixed cut. It has 50 facets, a high crown, stepped facets, wide corners and a small table, with a deep pavilion. Using a combination of step cut and a brilliant faceting on the pavilion, the cut produces a contemporary version of the cushion. A special setting has been made to showcase the Lucida cut.
