Wow. I will back you, ccsv - yes. Sometimes there are so many things that go wrong you have to triage what to deal with first and things like seams fall through the cracks. I believe you're right, whenever a person selling a product has specialized knowledge of their field (like your seam issue) the burden falls on them to explain it. You cannot know what you don't know since you haven't gone through it before - but they have. Many many times. So, don't feel bad. I do feel your pain and frustration though. That said, the kitchen looks great and I doubt it's worth risking the cabinets or the backsplash, etc.

Shannon_WI: Sorry, but when sinks are strapped in place, they become the vertical reinforcement for the front sink rail. Tops of any material have little flexural strength, no matter the width. This front rail is 2 3/8" wide, the sink is strapped, and I'll dance a Conga line across it anytime:

I can’t fit my hand behind the edge. What else could they be? They were there from the day of install. The fabricator told me to wait and see if they went away and dried out. They haven’t. He came over today and said he will have to tear out and I need to pick new stone.

They put the little machine on the full seam to make it tight, but I still thought it was wide. The other one at the sink was just pushed together by hand. I think they are a little wide as well. Yes, there must be a chip at the edge of that full same. I feel like they need to repair the chip and then do the seam. The black places were unexpected because we looked at this on slab Smith, but you cannot see the side of the stone. That is just part of the natural stone. There are some other black Crystal spots in the slabs in general. We Did the seam at the sink because we were working with two slabs and had to get everything out of that. I went in and looked at it on the computer and it looked great. I was surprised about the two little black crystal things, but there was just no way to see those on the computer. They are not some kind of weird filler. I don’t want to mess with them and try to chip them out because I feel like that will cause more problems. Bad luck that they just happened to be where we were matching up seams!
