No, they are quartz (specifics below)! We put marble in our kitchen in California and it was my biggest regret! It was such a pain to take care of – always scratching, staining and chipping, so I knew I didn’t want marble (even though I love the look!). I saw this countertop in a home, and was shocked when they told me it wasn’t marble…I was sold! It doesn’t have that “manmade” look, it looks so real and it doesn’t stain, scratch, or chip – YAAASSSS!
