The neighbor who sat on my granite countertop last Friday.....
is one lucky son of a gun!!!! Below are the after pictures from the repair. I have to say if I didn't know where the break was I would never have known about it. Thank you to oldryder & Trebuchet who gave me reassurance when I desperately needed it. It was greatly appreciated.
The installer did say there was a natural fissure at the corner which was the reason why it broke. If the fissure hadn't been there he said more than likely the corner wouldn't have broken off. But he did say no one should be sitting on granite counter tops regardless. Amen!
