When it comes to worktops, our clients are always surprised to hear that carrara marble and natural stone worktops don't usually cost more than corian or other manmade material worktops. In fact, often we find that marble worktops work out cheaper. Our marble worktops are supplied and fitted by the same specialised stone companies who we know and trust to do a fantastic job every time. Carrara marble especially is such a beautiful, natural product and works well with almost any style of interior. We would definitely recommend!

If you're still note sure, I found this great list of pros and cons of marble countertops on the The Kitchn.

Marble Countertop PROS

• Beauty - Classic, timeless beauty, and a white brightness not available in granite or soapstone.
• Cool Temperature - Marble is wonderful for working with pastry, since it is naturally cool; it doesn't conduct heat very well.
• Cost - While some rarer types of marble are very expensive, the more common Carrara (also called Carrera) marble is one of the least expensive natural countertops.
• Widely available - Unlike some quartzes and the hard-to-find quartzite, marble is available from nearly any stone fabricator or stone yard.

Marble Countertop CONS

• Scratching - Marble can scratch easily, especially when touched for a long period of time by something acidic. A slice of lemon laid down on a polished countertop overnight can leave a mark in the shape of the lemon slice, duller than the surface around it.
• Staining - Marble can also stain; red wine and some fruits are infamous for leaving indelible stains on the marble.
My Takeaway So Far: If you are OK with countertops looking a bit scratched up, and developing a patina of use over the years, then marble may be for you. If you want them perfectly glossy all the time, then perhaps not.
Also, I discovered that honed countertops (the more matte, less shiny finish that comes from abrading the stone) can be much more kitchen-friendly.
