Quartzite or marble: which belongs in your kitchen?

Stand a Taj Mahal quartzite next to a Calacatta marble and the family resemblance is obvious: a soft, light ground, gentle movement, the same quiet luxury. On a countertop, though, the two stones lead very different lives.

Quartzite is a metamorphosed sandstone, mostly quartz, which is harder than steel. It shrugs off knives, hot pans and lemon juice, which is why it has become our most requested kitchen material. Marble is calcite: softer, warmer to the touch, and reactive to acids. A splash of vinegar will etch it; a decade of family dinners will give it a patina.

Neither is better. A marble kitchen that is allowed to age gracefully is a beautiful thing, but the owner has to want the patina. If the idea of the first etch mark keeps you up at night, choose quartzite and sleep well.

The best way to decide is not a website. It is standing in front of the full slabs. Come walk the racks, put your hand on both, and see which one you keep coming back to.
