What Nobody Told Me About Brazilian Marble: My Cautionary Tale

Thinking about using Brazilian stone in your home? Before you commit, here’s what happened when my beautiful, Blanco Cachoeiro marble unexpectedly began rapidly oxidizing (and ultimately had to be replaced)…

They warned me about etches…

They warned me about chips and stains…

But no one prepared me for widespread discoloration (from normal, everyday kitchen use might I add).

Yes…marble countertops in my kitchen proved to be a freakin’ nightmare, but not for the reasons you would expect.

Instead of lamenting the occasional etch or stain, within a matter of weeks after having my Blanco Cachoeiro marble installed, I instead found myself watching large areas of my beloved stone counters slowly turn pink before my eyes…

I then spent the next six months advocating for myself (between the fabricators and the stone supplier) trying to get answers while learning far more than I ever wanted to know about oxidation in natural stone.

What Causes Natural Stone to Turn Pink?

At the time, I had never even freakin’ heard of natural stone oxidation. Like most people shopping for marble countertops, I assumed the biggest concerns would be etching, staining, or chips from everyday kitchen use.

But as I quickly learned during my panic-fueled research spiral (while watching my countertops change before my eyes despite absolutely babying them), certain natural stones can contain iron deposits beneath the surface. And from what I learned throughout this process, some heavily mineralized Brazilian stones can naturally contain higher levels of iron content than other marbles.

When exposed to moisture over time, those iron minerals can oxidize- leading to rust-colored or even pink discoloration within the stone itself.

Ironically, the very things I fell in love with in my slab, all the natural movement, variation, and crystal clusters, may have also been what made it more susceptible to oxidation in the first place.

Now to be fair…oxidation-related discoloration in natural stone is not completely unheard of. In some cases, rust staining can occur when stone is repeatedly exposed to metal or excessive moisture (like in showers).

But what made my situation so alarming was that the oxidation was occurring internally throughout the stone itself during completely normal kitchen use (despite the fact that I followed proper marble care guidelines and only used marble-safe cleaners on my countertops).

Oxidation (Not Just a Marble Issue):

What surprised me most was learning that this issue is not necessarily limited to marble alone. During conversations with the stone supplier, Cosentino (who I will never use again) explained that they had previously seen oxidation-related issues occur in certain granite installations as well. And while researching the issue myself after the discoloration began spreading, I also came across cases of quartzite developing similar oxidation problems over time.

Can Marble Oxidation Be Fixed?

When the discoloration first started and was still relatively localized, the fabricators had me try a poultice made from baking soda and hydrogen peroxide. And although it was time consuming and messy as hell, it actually did help lighten some of the affected areas.

But as soon as I felt like I had one spot under control, another would decide to rear its ugly head (even in areas never exposed to moisture). So once the poultice efforts turned into a game of whack-a-mole, I had to have a hard conversation between the installers, the stone suppliers, and the company I had insured my stone through.

Ultimately, I was told that fully remediating the oxidation would likely be more invasive than simply replacing the stone itself. And even then, there was no guarantee the remediation would permanently solve the issue.

And while neither the stone supplier nor the insurance company initially wanted to accept responsibility, after months of advocating for myself and fighting to have my material warranty honored, my replacement countertops were finally covered. At that point, I was more than ready to move the eff on with my life…

Would I Use Marble Again?

What made the replacement process especially difficult was realizing there were really no guarantees with any natural material. At one point during the process, I was even warned that oxidation-related issues could theoretically happen with almost any stone surface (including quartz).

So given that I was f*cked either way, I decided to be brave and just follow my heart…

And unfortunately for my nervous system, the heart wants what the heart wants. So… I chose marble again…

But not Brazilian marble this time… Carrara marble sourced from Italy (which I will be revealing installed in my kitchen soon here on the blog).

At the end of the day, I will probably never truly know why my oxidation case occurred at such an extreme level or who was ultimately to blame.

Did the supplier fail to fully dry the slab before sealing it? Was the iron content within my particular slab simply too high for a functioning kitchen environment? Or are certain heavily mineralized Brazilian stones simply more susceptible to oxidation issues?

Both for my own sanity and for anyone reading this considering Brazilian stone (or honestly, any natural stone for that matter), I truly hope my situation was simply some unfortunate fluke. That said, it’s still something I wish someone had warned me about beforehand ( if only to preserve my sanity during the endless amount of subtle gaslighting and insinuation throughout the process that somehow this was all my fault).

So…consider this my civic duty as a mildly traumatized DIY interior design blogger: opt for lower iron-content stone when sourcing your slabs, advocate for yourself if this begins happening to you, and understand you may still get screwed either way.

Thank you so much for stopping by and spending some time with me this week. If you found my ranting helpful, it would mean so much to this small business of mine if you could share it with a friend or “pin it” on Pinterest…

Until next time, keep on designing a life that feels as good as it looks!
