Sequoia Brown is a Precambrian Brazilian natural stone of the quartzite/marble family with a dramatically wood-grain-like band structure in dark brown, warm beige and grey wave tones — an expressive metamorphic stone that owes its trade name to the grain of the sequoia tree. Suited to designed wall claddings, floor surfaces, kitchen worktops, bar counters and prestige statement display surfaces.
Petrographically a Precambrian metamorphite on the boundary between marble and quartzite — assigned in the trade to the quartzite family.

About Sequoia Brown
Sequoia Brown is one of the most expressive Brazilian movement stones on the European market — a Precambrian metamorphic stone with a characteristic band structure that recalls directly the annual grain of a giant sequoia. Characteristic is a warm dark brown to almost black ground effect, run through with undulating flowing bands in warm beige, light brown and grey tones — the parallel vein bands follow a continuous direction and create a lively slab image reminiscent of wood fibre. At ROSSITTIS we carry Sequoia Brown for designed wall claddings, prestige floor surfaces, lobby areas, kitchen worktops, cooking islands, bar counters, vanity tops, display counters, fireplace surrounds, columns, table tops and project-specific special fabrications with a wish for a strong, wood-like movement signature.
Geologically, Sequoia Brown is a Precambrian fine-grained metamorphite from the Brazilian deep-metamorphic provinces — the petrographic classification of the material is not entirely uniform on the market: some sources classify the material as a marble, others list it partly as a quartzite, partly as a marble, with aliases such as Sequoia Brown Quartzite, Sequoia Brown Marble, Sequoia Brown Limestone and Sequoia Brown Woodstone. This ambiguity of classification is typical of Brazilian Precambrian metamorphites on the boundary between marble and quartzite — they contain both quartz and carbonate mineral fractions in varying proportions. In the international stone trade such materials are often assigned pragmatically to the quartzite family, since technically they behave closer to quartzite than to classical marble — more acid-resistant and more robust.
Technically, Sequoia Brown behaves like a high-quality metamorphic hard stone of the quartzite family: solid to high compressive strength, low water absorption, extensive acid resistance. The wood-grain band structure is characteristic of the material and not a quality feature that can be altered by selection; during installation, deliberate slab alignment with the band direction can be used as a design device — much as with the grain of real timber. Compared with classical timber-imitating stones such as Sequoia Brown Light, Wood Stone or Brown Wood, the band structure is expressive and rich in contrast; compared with classical Brazilian quartzites such as Taj Mahal, the appearance is dramatically darker and more linear in its movement.
At ROSSITTIS, Sequoia Brown is available as a raw slab (random size), as a floor tile, as tread and riser, as a window sill, as a skirting, as a wall facing and as project-specific cut-to-size work; likewise as a kitchen worktop, bar counter, vanity top and table top. The finishes currently available from stock are listed in the »Finishes« block further down this page.
Our frank assessment: Sequoia Brown is an architectural statement material with one of the most unique material signatures in the Brazilian natural stone range — the band structure resembling timber grain is almost unmistakable on the stone market and creates a warm, nature-like atmosphere. For projects that want to combine the robustness of stone with the appearance of timber, Sequoia Brown is a very strong choice. For sampling we recommend a selection from real slab images and, where appropriate, slab arrangement along the band direction — it is precisely the individual band intensity that makes the character of this stone.

Finishes
Sequoia Brown is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Satin-honed
The surface is brushed — softer minerals are removed in a targeted way, creating a slight depth and a matt appearance. Veined quartzites gain a special character in this way. Acid-resistant and scratch-resistant, easy to care for in daily use — a popular alternative to a polish in modern kitchens and living spaces.
Care & fabrication
As a Brazilian metamorphite of the quartzite/marble family, Sequoia Brown can be cared for without difficulty. Because of the ambiguity of its petrographic classification (marble and quartzite fractions), we recommend cautious care on an acid-sensitive basis, even though the material behaves predominantly like a robust hard stone. Immediately after installation we recommend a sealing treatment based on silane or polysiloxane — it protects against stains from red wine, coffee, oil or tomato sauce and reduces water absorption. Ongoing cleaning is carried out with a pH-neutral natural stone cleaner and a soft microfibre cloth or mop. Absolutely avoid acidic cleaners (vinegar, citric acid, descalers), aggressive all-purpose cleaners and abrasive steel wool — they can attack the carbonate fractions and leave matt patches over time. Take up acids spilled on kitchen worktops promptly. Frost-resistant outdoors (under cover is optimal). We recommend refreshing the sealing treatment every three to five years.
Frequently asked questions
Is Sequoia Brown a marble or a quartzite?
Petrographically, Sequoia Brown lies on the boundary between marble and quartzite — some sources classify the material as a marble, others partly as a quartzite, partly as a marble. This ambiguity is typical of Brazilian Precambrian metamorphites with mixed quartz and carbonate fractions. In the stone trade Sequoia Brown is mostly assigned to the quartzite family, because technically the material behaves closer to quartzite than to classical marble.
What does the name “Sequoia Brown” mean?
“Sequoia” refers to the Californian redwoods (Sequoia sempervirens and Sequoiadendron giganteum), whose characteristic red-brown trunk grain resembles the wood-grain band structure of this stone. The trade name describes the linear movement, reminiscent of wood fibre, that gives the material its own signature.
What other designations does Sequoia Brown carry?
On the market the material runs under Sequoia Brown Quartzite, Sequoia Brown Marble, Sequoia Brown Granite, Sequoia Brown Limestone, Sequoia Brown Woodstone, Sequoia Marrone Marble and Brown Sequoia Marble. All designations refer to the same Brazilian metamorphite.
What finishes are available in Sequoia Brown?
The finishes currently available from stock are listed in the »Finishes« block on this page.
Is Sequoia Brown suitable for kitchen worktops?
Yes, with moderate reservations. Because of the mixed mineral composition (quartz + carbonate), spilled acids such as wine, lemon juice or vinegar should be taken up promptly in order to avoid matt patches. With good sealing and careful maintenance, the material is very well suited to kitchen worktops and heavily used display surfaces.
Sequoia Brown or real timber — which suits better?
Real timber has the unmistakable warm material signature with trunk grain, but is sensitive to water, heat and acids — problematic in kitchens. Sequoia Brown offers a very similar visual timber quality in a more robust natural stone: heat-resistant, largely acid-resistant, stain-resistant (with good sealing). For statement display surfaces with a timber look in the robustness of stone, Sequoia Brown is a very powerful design choice.
How do I clean and care for Sequoia Brown?
Daily care with a pH-neutral natural stone cleaner and a soft microfibre cloth. Avoid acidic cleaners and aggressive all-purpose cleaners. A sealing treatment based on silane or polysiloxane after installation protects against staining; refresh it every three to five years.
What does Sequoia Brown cost?
The price depends on the batch, thickness, surface finish and fabrication — with natural stone there is no serious flat rate per square metre. Business customers see prices once their B2B account is activated; private customers receive a complete quote through a fabricator near them.
