Not sure of the name of his website, but definitely look up Brian Gavin. He did my recut while he was still at Whiteflash, and he''s incredible! Whiteflash also used to do recuts, I''m not sure if they still do, but it''s worth looking into.
I think Wink can put you in touch with Infinity Diamonds for recuts as well. I think it is called High Performance Diamonds. http://www.highperformancediamonds.com/
