Polishing Cesar Stone

I have a customer who is taking over a problem with a piece of cesar Stone (http://g603.net) . It has an approximate 2" bevel all around that appears to have a matted finish. The top of the piece has a nice shiny finish and (http://maplered.com) they want to match the bevel to the top. If it matters, the Stone (http://g603.net) is red with tiny flecks of silver (like glitter). Any suggestions? Thanks for your help.
