If its got brown in it, it is St. Laurent. Treat it like nero marquina. It can orange peel easy so be careful on the acid..It should polish pretty easy.

Good Morning All:

Attached are a couple pics of marble top that I am bidding on. Is it Black Gold, Noir St. Laurent, or Nero Marquinha? Also, I have a vague memory (most are anyways) that I should treat this a little differently. Thanks
