Take a sample home and put lemon juice on it. What you will find is that the etches on dark marble show up white. Not at all attractive. And that's why only the white marbles are truly popular for kitchen counters. They show etches much less than the dark ones. Possibly use it as a vertical accent somewhere in your home (NOT a shower), but I wouldn't use it on any horizontal surface. Maybe a gorgeous full height backsplash where you have no uppers on a wall....or in an entry way directly facing you as a focal point. Think of it as art, not a work surface.

I looked at the brochure but I could not find exactly what color or pattern Caesarstone has in India. I'd like the look of a "marble" Caesarstone for the counters and the back splash with your blue cabinets. I don't know if this is possible, though. I have granite in my kitchen and I the have counter and back splash in the same granite and I have loved it for 15 years. Do they have induction cook tops in India? They are wonderful, too.

quartz is a man made product using natural stone and a resin material. No sealing and is stain proof. I have had my granite for 10 years. I have never had a staining issue and set hot pots down on it seldom, but it has never bothered it. I've sealed it maybe 2-3 times over 10 years. granite really doesn't stain. So, compared to quartz, they are very similar. It all comes down to what you like the best.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?
