Wo der Stein
auf den Berg trifft.
Wir beschaffen nicht aus Katalogen. Unser Team besucht über 30 familiengeführte Steinbrüche in 10 Ländern, wählt jeden Block von Hand aus und pflegt Beziehungen, die in Jahrzehnten gemessen werden — nicht in Transaktionen.
We evaluate quarries the way
architects evaluate stone:

French limestones are specified by architects for their consistent bedding plane structure. Our Pierre de Bourgogne selection focuses on frost-resistant grades.
Portugal
The Estremoz marble belt (Alentejo) is a Cambrian-Silurian metamorphic sequence (~400 Ma) — among the oldest commercial marbles in Europe. Portuguese limestone (Moca Creme) is Cretaceous (~100 Ma) from the Lisbon region.
Diamond wire for marble — Estremoz quarries are among the deepest in Europe (60–100 m benches). Chain saw for limestone.
Estremoz marble: 2.6–3.0 × 1.3–1.6 × 1.2–1.5 m, 16–21 t. Moca Creme: 2.4–2.7 × 1.3–1.6 × 1.1–1.3 m, 13–17 t.
Estremoz / Borba / Vila Viçosa (Alentejo), Sintra (Lisbon), Ançã (Coimbra)
Sines, Lisbon, Setúbal.
Estremoz marble's fine grain structure makes it ideal for sculptural and architectural millwork. We track block colour consistency batch-to-batch.
Tunesien
Tunisia's stone resources span Jurassic (~160 Ma) marbles in Chemtou and Cretaceous (~100 Ma) limestones in Thala and Kesra. The Chemtou deposit (Giallo Antico) was quarried by the Romans for monuments across the empire.
Diamond wire for marble; mechanical excavators and chain saw for softer limestone.
Limestone: 2.4–2.8 × 1.3–1.6 × 1.1–1.3 m, 12–16 t. Marble: 2.5–2.8 × 1.2–1.5 × 1.1–1.4 m, 14–18 t.

Radès (Tunis), Sfax, Bizerte.
Tunisia is our growth frontier. We invested heavily in local partnerships from 2022 — bringing Tunisian stone to international specifications.
Iran
Iran holds some of the world's richest onyx and travertine deposits — banded calcite laid down by mineral hot springs from the Neogene to the present around Azarshahr and Mahallat, alongside Cretaceous limestones and granite massifs of the Zagros belt near Isfahan.
Diamond wire for travertine and marble benches; careful chain-saw and wire extraction for fragile onyx lenses, which occur as pockets rather than continuous beds.
Travertine: 2.4–2.8 × 1.3–1.6 × 1.0–1.2 m, 12–16 t. Onyx: smaller irregular blocks, typically 3–8 t, selected individually for banding and translucency.
Azarshahr (East Azerbaijan), Mahallat (Markazi), Natanz (Isfahan), Abadeh (Fars), Dehbid (Fars)
Bandar Abbas; overland via Türkiye to Mersin and Izmir for Mediterranean consolidation.
Iranian onyx and travertine are graded at the yard for banding and translucency before purchase — we consolidate shipments through our Izmir facility.
Indien
Indian marble (Rajasthan) is Precambrian (~800 Ma) — recrystallized from carbonate platforms of the ancient Aravalli range. Indian granites are among the oldest exposed rocks on earth at ~2,500 Ma (Archean).
Drill-and-blast for granite blocks with diamond wire secondary cutting. Diamond wire for marble. Gang saw processing at mill yards.
Granite: 3.0–3.5 × 1.6–2.0 × 1.5–1.8 m, 22–28 t. Marble: 2.5–3.0 × 1.3–1.6 × 1.2–1.5 m, 16–22 t.

We source only from quarries with valid environmental clearance and labour compliance certifications. Granite block selection is done at the yard after washing.
Brasilien
Brazilian granites and quartzites are Precambrian (~2,000 Ma to ~1,500 Ma) — among the hardest, most durable stones in commercial use. The Bahia region yields unique blue granites coloured by sodic amphibole inclusions.
Drill-and-blast primary breakage, diamond wire secondary cutting. Block sizes are larger than Mediterranean norms due to massive deposit geometry.
Granite: 3.2–3.8 × 1.8–2.2 × 1.6–2.0 m, 25–32 t. Quartzite: 2.8–3.2 × 1.5–1.8 × 1.4–1.7 m, 20–26 t.
Feira de Santana / Ceará, Macaubas (Bahia), Bahia interior, Espírito Santo
Vitória (major granite export hub), Salvador, Santos.
Brazilian quartzite requires specialized processing tooling (diamond-impregnated blades). We work exclusively with processors who certify blade pressure and feed rate.
How the stone
comes out of the ground.
Diamond Wire Sawing
Marble, Granite, QuartziteA diamond-impregnated steel cable loops through drilled pilot holes and cuts through the rock mass at 6–12 m²/hour. Produces clean block faces with minimal micro-fracturing — essential for high-yield marble extraction.
Chain Saw Cutting
Limestone, TravertineA hydraulically powered cutting arm with tungsten-carbide teeth — similar to a oversized chainsaw — kerfs vertical and horizontal cuts in softer stones. Preferred for limestone benches where diamond wire would overheat.
Drill & Blast
Granite, Hard QuartzitePrecisely angled boreholes charged with low-vibration explosives to separate massive granite blocks from the bedrock. Modern micro-delay detonators control fracture propagation to within centimetres.
Helix / Vein Cutting
Premium MarbleA specialized diamond wire technique that follows the natural vein orientation — rather than cutting across it — to maximize the commercial value of figure-veined stones like Calacatta and Statuario.

Ranges represent commercially available block sizes. Actual dimensions vary by quarry and deposit geometry.
The dust settles differently in a marble quarry. It's fine, almost chalky — it gets into everything, but it never feels dirty. Just old. I was in the Apuan Alps last October, standing on a bench that had been worked continuously since the Romans. The quarry master — third generation — pointed to a face and said, "My grandfather cut that wall. My father cut beside it. I'm still following the same vein." He wasn't being sentimental. He was telling me that the stone dictates the schedule, not the other way around.
That's what we look for. Not the biggest quarry or the cheapest block, but the quarry master who can read the geology in the colour of the mud on his boots. That knowledge is irreplaceable. You can't scale it, you can't automate it, and you can't fake it in a PDF.
The scale behind
the selection.
Our sourcing footprint spans the Mediterranean basin, the Indian subcontinent, and the Brazilian shield. Each region selected for its geological distinctiveness — no two countries in our portfolio produce interchangeable stone.
From the Mediterranean
to the New World.
