Marble Polishing Problem

I was hiking in the Carrara marble quarries this summer. I picked up some specimens of black and white marble. I tumbled them in coarse, medium, and polish grits for 7 days each and then 4 days of burnishing. I was hoping that they would have a glassy shine but they only have a satin finish:

Any suggestions on how I can get them to polish up to a gloss?
