Let’s be real: not all stone is created equal. Between spills, splatters, and life’s little messes, your surfaces handle more than you might think. So, how do heavy hitters like marble, quartzite, and porcelain stack up?
To find out, designer Meredith Stern got her hands dirty with an at-home surface durability experiment. Armed with everyday stain offenders, think red wine, coffee, lime juice, and tomato paste, she tested them on sealed and unsealed samples of each material. The results? Eye-opening and incredibly useful if you’re designing for real life. Read on as we break it down.


Marble: Drama, With Easy Upkeep
Marble is the queen of bold beauty; veined, luxurious, and impossible to ignore. But, it does require proper care. Porous and sensitive to acids, marble will etch and stain if left unsealed. That doesn’t mean it’s off the table, but it does mean sealing is non-negotiable.


Meredith’s Test:
Calacatta Viola handled staining like a champ (no marks after 24 hours), but both sealed and unsealed samples etched. The lighter Statuary Marble? The unsealed version picked up some stains.
Use it when:
You want wow-factor, especially in bathrooms, fireplaces, or powder rooms. Kitchens are fair game, too, but only if your clients are careful and have a strong maintenance plan.
Quartzite: Strength You Can Style With
Quartzite is what happens when natural beauty meets serious durability. It looks like marble but handles like stone with a backbone. It’s heat-resistant, harder than granite, and perfect for clients who want the look without the worry.


Meredith’s Test:
Cristallo Quartzite was flawless with zero stains and zero etching. Taj Mahal Quartzite passed the test too, though the unsealed sample had slight staining from red wine and coffee. Still, nothing a proper seal wouldn’t solve.
Use it when:
You’re designing a high-traffic kitchen, outdoor bar, or anywhere style and strength need to go hand in hand.
Porcelain: Practically Indestructible
Porcelain slabs are the industry’s best-kept secret. They don’t stain. They don’t etch. They don’t care if you spill wine at 10 p.m. and forget to clean it up. Plus, they come in endless finishes that mimic natural stone, metal, and more.


Meredith’s Test:
Taj Mahal porcelain didn’t blink. No stains. No etching. Sealed or not. Total perfection.
Use it when:
You want the look of natural stone with zero stress. Especially great for outdoor kitchens, poolside bars, busy countertops – basically anywhere durability matters.
The Bottom Line
Natural stone is still the gold standard, as long as it is properly sealed and maintained. If your client needs a worry-free surface that still brings the drama, porcelain is a no-brainer.
