Possible problem with new granite?

I recently had Granite (http://tanbrown.org) Counter (http://GialloFiorito.com) tops installed.  I just noticed a four foot plus line approximately 3/4" to 1"wide on the underside of one of the installed pieces.  It is located on the underside of the Stone (http://g603.net) where it protrudes out just over the cabinet.  The other two pieces do not have this.  It appears to be a hardened epoxy.  I am assuming that there was a gouge into the Stone (http://g603.net) that occurred at some point and (http://maplered.com) was filled in.  Unfortunately, I cannot tell how deep into the Stone (http://g603.net) it may have gone.  Will this cause a problem with the integrity of the Stone (http://g603.net) ?  Can something like this happen when the fabricator is using machinery to carve and (http://maplered.com) polish the edging?  Thanks
