Hello, im in the process of looking for a diamond and really like the Tiffany Lucida. I have found several jewlers who reproduce the setting but nobody who reproduces the actual Lucida diamond cut. I have heard that the Radiant is the most similar. Can someone advise please. Also, im looking to pay less than 12K for a D-F and IF-VS2 diamond w/ a platinum Lucida setting. Is that a realistic price range for my specifications? Please advise. Thank you.
