Dolomite

A huge share of what gets sold as marble in American showrooms isn't marble at all.

It's dolomite, or dolomitic marble.

Dolomite is a different mineral, calcium magnesium carbonate, and it's harder and much less acid reactive.

So when someone tells you their marble countertop has been fine for years, you have to ask, is it actually

marble? That's the dirty secret of the stone yard.

The label on the slab says marble, but the geology says something else.

And Dolomite behaves differently enough that it explains a lot of the testimonials.

People think they've discovered that marble is tougher than everyone says, when what they've actually discovered is that they bought a different rock.

I'm going to tell you, but he wasn't a rapper though.

Nigga, Dolomite.
