Have rust problem? Description

I have had new Counter (http://GialloFiorito.com) s installed just a week ago. The Material (http://g654.org) is Calcutta White Marble.    It looked beautiful when installed, however, four days after installation round rust colored specs and (http://maplered.com) spots started to appear. These spots are not near veins but in the middle of the white part of the Marble (http://www.lightemprador.com) .   There are many of them. Is their a Stone (http://g603.net) product you would recommend to try to remove or reduce the intensity of the spots?
The Stone (http://g603.net) is not yet sealed.
Also, even if I am successful in reducing or removing the spots, will more spots appear after the Material (http://g654.org) is sealed?   My fabricator is surprised that the spots appeared so quickly and (http://maplered.com) are not located on or near veins.
Thanks for the advice.
Pat.
