Who can see my FOB price?

Only approved buyers you are in conversation with, and Rosso administration. It is never public, never visible to designers, and never used to derive anything shown in the public catalog.

Does Rosso Stone buy or resell my material?

No. Rosso Stone connects supply to buyers and keeps the record trustworthy. Price, payment terms and shipping are agreed directly between you and the yard.

Do I need photographs to a professional standard?

Better imagery converts better, and the standard asks for full-slab scans, natural light, close-ups and edges without filters or watermarks. But you start with what you have. We tell you what is worth reshooting rather than blocking you at the door.

Do I need to speak English?

No. The platform runs in Portuguese and English, and the material records are presented to buyers in their language. Talk to us in Portuguese from the first message to the last.

Publishing material and being found is free, permanently. A paid tier is planned around intelligence and sourcing tools, and founding partners get their terms locked before it exists.

What is required for approval?

That you are a real operation with material you can actually deliver, and a person to reach when a buyer has a question. The review is a conversation.

For quarries & exporters

Your material, in front of the U.S. yards that buy it.

American yards buy from across an ocean on photographs and trust. Rosso Stone gives your material, your capacity and your export availability one place where approved buyers can actually find them, with your FOB pricing restricted to that conversation.

What we commit to

Where your information goes, and where it stops.

Supply-side pricing is the most sensitive thing on this platform. The boundaries around it are product decisions, built into how the platform works.

Your FOB price is not public.
Commercial pricing lives on one axis only: you, the approved buyer, and Rosso administration. It never appears in the public catalog, and designers never see it. What they see is a relative price point on the U.S. inventory. Your export price stays out of it.
Approved buyers only.
Stone yards and distributors can set up their account immediately. Seeing supply-side FOB offers waits on company verification. Describing yourself as a buyer at signup grants nothing on its own.
Listing is free. Permanently.
Publishing your materials and being found is the infrastructure of the marketplace. Any paid tier that appears later covers intelligence and tools. The visibility of your material stays free.
Portuguese is a first language here.
Country, language, currency and international logistics are first-class concepts in the product. The Brazilian side is built to carry the same weight as the American one, with its own journey and its own terms.

How it starts

Three steps, and the heavy one is ours.

You are not being asked to learn a system or build a catalog. Send what you already send buyers today, and we turn it into records that hold up on the other side.

01
Create an account
You enter the Studio immediately and start setting up. Company verification runs in parallel — the same review that keeps FOB offers on the buyer side worth something.
02
Send your materials as they are
Exclusive materials, new releases, production capacity, blocks and bundles available for export, photographs. A spreadsheet, a PDF or a message all work. We normalize it into the standard the buyers see.
03
Approved yards see the offer
Requests and questions come back to you directly, with the commercial conversation staying between you and the buyer. Rosso Stone never buys or resells your material.

As the platform fills up

What the U.S. side can tell you.

This is the part that has no equivalent anywhere else, and the part that needs real usage before it is honest to show. The sequence, plainly:

What American designers are actually specifying
Which materials get searched, saved and specified in the U.S., by region and by application. It is a signal about extraction and production decisions that today reaches quarries months late, through the buyer, if at all.
Unmet demand
Materials designers look for and cannot find available anywhere in range, including the searches that return nothing at all. That is a purchase argument you can take to a yard.
Container planning
Mixed-load planning against real weight limits, so a buyer can assemble a container from more than one material without doing it in a spreadsheet. In design; the phase is not fixed yet.
Verified records
Tiered verification of inventory, dimensions and imagery, so material that is documented properly is visibly distinguishable from material that simply claims to be.

None of this exists in useful volume on day one, and we won't present it as if it does. What is real today is being present, correctly documented, in front of buyers who are approved by hand.

Founding partners

Early suppliers shape the standard.

The submission standard is being written now: what a slab record must carry, which photographs count, how capacity is described. All of it written against real quarry operations.

We set up your first materials and offers ourselves, at no cost.
Preferential terms locked in before any paid tier exists.
Direct influence on the submission standard and on what the buyer side sees.
Everything in Portuguese, with a named person on the other end.
