Repairing crack/fisure in ubatuba

I,ve got a crack/fisure in ubatuba in the sink front. the piece is still in the shop on the table. Was not there until after the sink was cut, not polished yet. I ran CA into the crack until it couldnt take anymore, top polished, now looks good. the Stone (http://g603.net) shifted up just bearly enough to feel, now after polish you cannot feel it. When I pick up on the slab in the middle of the sink hole by hand (http://maplered.com) there is no movment noticable. Do you think its ok? Its rodded with fiberglass rods with touchStone (http://g603.net) epoxy. Seems ok to me just want an expert opinion. Damn ubatuba
