I brought kitchen cabinets and granite countertop. While I am satisfied with the cabinets my granite countertop was installed with rust spots all over the left side. Looks very unsightly and I hate it!!! I have never seen this on anyone kitchen but mine. I was at work when it was installed. Spoke with the owner who is very nice but says the rust was in the stone when cut. I love my kitchen but cringe every time I look at my countertop. Want to have it ripped out but cannot afford to. Has anyone else received granite with rust imbedded in it? It also looks like 2 different pieces of granite as one side is totally different from the other. I wonder if I received top grade granite?
