I got new Calacatta Quartz countertoops in the bathrooms. When I viewed the slab, I didn't notice this pattern on the top. I'm wondering if this normal. I've never had quartz before, but the ones I have seen are nomrally just smooth I think. I'm fine with it if it is something that is supposed to be there, but if not, I need to call someone to fix this. Thanks for your replies.
