How to repair a large crack in my Granite (http://tanbrown.org) Counter (http://GialloFiorito.com) top

I have a Granite (http://tanbrown.org) Counter (http://GialloFiorito.com) top island (http://maplered.com) that tipped over and (http://maplered.com) now has a large crack and (http://maplered.com) is almost broken completely.  The crack is approximately 4 feet long and (http://maplered.com) the first 12 inches of the crack went all the way through the slab and (http://maplered.com) the remaining 3 feet does not appear to be cracked all the way through.  Is there a way to repair this crack?  This slab was about to be installed.
