Floors
High-traffic floors in lobbies, halls, and corporate spaces — high mechanical strength.
The rarest blue among stones —
waves of sky crossed by sand and gold.
Azul Macaúbas is a Brazilian quartzite of rare blue — from sky to deep denim — formed in wavy layers that alternate white and pearl-grey bands with fine golden veins. A massive structure, fine-to-medium granulation, and an essentially quartz matrix: the basis for high hardness and the serene brilliance of stones formed under high pressure.
It is an exceptional material, for projects that want an unforgettable focal point. It pairs beautifully with warm woods, brass, whites, and greige neutrals — taking center stage on a wall, island, or fireplace. Under natural light, the blue gains the depth of water.

Every Azul Macaúbas slab carries the chromatic vocabulary nature spent millions of years writing — from deep navy to the pearl white of its bands, crossed by fine golden veins.
High-traffic floors in lobbies, halls, and corporate spaces — high mechanical strength.
Feature walls, islands, tables, and panels — a scale that showcases the veins.
Bathrooms, powder rooms, and kitchens — low absorption (< 1%) with proper sealing.
Façades and patios — a K coefficient near 1 ensures stability against weathering.
Each Azul Macaúbas slab carries an unrepeatable signature. Our intent is to inspire new readings of color and expand the vocabulary of combinations in kitchens, living rooms, bathrooms, and façades.

Certificates CEPED nº 198.1–198.6/2020 (CEPED — Centro de Pesquisas e Desenvolvimento (BA)) does not include a petrographic analysis; the sample is identified in the report as Quartzite — Dimension Stone.
Physical indices — average values of 10 specimens (Certificates CEPED nº 198.1–198.6/2020).
Mechanical strength tests performed on dry samples (Certificates CEPED nº 198.1–198.6/2020).
Linear thermal expansion determined according to ABNT NBR 15845:2015 (Certificates CEPED nº 198.1–198.6/2020).
Average values from Certificates CEPED nº 198.1–198.6/2020 — CEPED — Centro de Pesquisas e Desenvolvimento (BA). Results apply to the tested samples. Validation of structural design and fastening by the engineer of record is always recommended, taking into account natural variations between batches and slabs.
Azul Macaúbas is a quartzite: a natural stone with Mohs hardness 7, highly scratch-resistant and low in porosity. Because it is natural — not engineered quartz — it needs periodic sealing and a gentle cleaning routine to keep its shine for years.
A soft microfiber cloth or non-abrasive sponge, warm water, and neutral detergent. Always dry after cleaning and wipe up spills right away.
Seal with a quality water-repellent, reapplied every 6 months to 2 years depending on use — the barrier that repels liquids and eases cleaning.
Heat-resistant, but thermal shock can cause micro-cracks. Always use trivets — never rest a hot pan directly on the stone.
Don't cut directly on the surface — it dulls both the shine and your knives. Use a cutting board and avoid dropping heavy objects.
After installation, wait about 24h before using the surface (curing of adhesives and sealants). Always check the instructions from your quartzite's manufacturer and the fabricator responsible for specific guidance.
