You've been burned by
inconsistent stone before.
Slabs arrive 3mm over dimension.
Your installer discovers it on-site. The recut costs $1,200 and pushes the kitchen two weeks.
Lot 2 doesn't match Lot 1.
You ordered 400 sq ft in April. You need another 120 in September. The supplier says "same color." The slabs say otherwise.
Lead time quoted at 6 weeks. Delivered at 14.
Your GC has the tile crew scheduled. The cabinet installer is standing by. The stone isn't here.
No ASTM data. No test certificates.
The spec calls for C615 granite. Your supplier sends a brochure. The architect's rep asks for lab results. You have nothing.
One that starts 200 meters underground.
We don't buy stone.
We own the mountain.
Every step from extraction to surface finishing happens under our roof. That's why we can guarantee batch consistency, hit dimensional tolerances, and give you a real lead time — not an estimate from a broker.
Extraction
Controlled bench blasting. No middlemen.
We operate 14 active quarry faces across Brazil, Portugal, and Norway. Every block is GPS-tagged at the face, photographed, and entered into our material tracking system before it leaves the site.
Block yield: 18–22 m³ per extraction cycle. Overburden ratio maintained below 4:1.

Primary Cutting
Diamond-wire saw. Consistent block geometry.
Blocks are cut to slab form at our primary processing facility within 72 hours of extraction. Wire saw kerf is 6mm — tighter than gang saw, yielding more slabs per block and more consistent thickness.
Target slab thickness: 20mm ± 0.5mm. Thickness uniformity verified at 9 measurement points per slab.

Surface Finishing
Four finishes. One facility. Zero hand-off variation.
Polished, honed, flamed, and leathered finishes are all applied in-house. Because we control the abrasive sequence, a honed finish from Lot 12 matches a honed finish from Lot 47. Calibrated to a 40-grit final pass for honed, 3000-grit for polished.
Surface flatness: ≤ 1.5mm over 1200mm span. Gloss units (polished): 85–95 GU per ASTM C97.

QC & Dispatch
Every slab photographed. Every batch documented.
Before any slab ships, it is photographed against a calibrated reference tile from the same extraction lot. Color deviation is measured via spectrophotometer. Slabs outside ΔE 2.0 are flagged and held — not shipped.
Batch documentation includes: lot number, quarry GPS, extraction date, finish type, ASTM test batch reference.

Real stock.
Photographed this week.
Every slab in our inventory is photographed against a calibrated reference tile. What you see on screen matches what arrives on your site. Batch numbers are printed on every pallet.
Batch Color Guarantee — In Writing
If your reorder lot deviates beyond ΔE 2.0 from the original batch, we replace the material at no charge. No RMA hoops. No restocking fees.

From the people who put
our stone in the ground.
"We spec'd Quarry for the Meridian Tower lobby — 4,200 square feet of honed Nero Assoluto. Every slab arrived within 0.3mm of the drawing dimension. First time in twelve years I haven't had a site callback on stone."

"The batch guarantee is real. We ordered 340 sq ft in March, came back for 80 more in August. The stone matched. I've framed the spec sheet — it's the only supplier document I've ever trusted."

"Municipal hardscape specs are unforgiving. The park commission requires ASTM C615 compliance documentation on every submittal. Quarry sent test certificates with the first quote. Nobody else does that."
