How to Choose a Marble Inlay Manufacturer
Inlay is unforgiving of a weak maker. These are the five checks that separate a real factory from a reseller — and what each one should look like.

Most marble inlay is bought as a bespoke commission, often from overseas. That makes the choice of maker the single biggest risk in the project — and it is a risk you can largely remove by asking five questions.
The right maker is a factory, not a broker. That means the drawing, the waterjet, the hand-bench and the dry-assembly floor all sit under one roof, so the tolerances actually hold and there is no drift between the drawing and the stone. The five checks below are what that looks like in practice.
Start with the drawing. A real maker engineers your design — setting it out full size and cutting from your own file — rather than reselling a stock panel from a catalogue. Then ask for the tolerance: ±0.1mm at the waterjet, closed further by hand, is what makes joints disappear rather than read as a grout line.
Next comes the material study. Expect a cut plan and a slab selection against your drawing before any stone is cut, and photograph the dry assembly of the whole composition before it is crated. If a maker cannot show you those, they cannot control the outcome.
Ask each maker for evidence, not assurances. The ones who can show a full-size drawing, a material study, dry-assembly photography and their own factory floor are the ones to trust with a bespoke floor. Everything under one roof is what keeps the tolerances honest.

From drawing to crating
Full-size drawing
The pattern is drawn 1:1 on the atelier floor before any stone is cut, so proportions are settled at the scale you will walk on.
Stone selection
Blocks and slabs are chosen against the drawing, vein by vein, and photographed for your approval.
Waterjet cutting
Multi-axis waterjet cuts every piece direct from the approved CAD file, held to ±0.1mm across the whole figure.
Dry assembly & crating
The composition is assembled, inspected and numbered on the factory floor, then crated with a setting plan.
Answered for specifiers
Ask for dry-assembly photography of a previous job, and a video call on the factory floor is reasonable for a large commission.
±0.1mm at the cutting stage is what good makers hold; anything looser shows as an open joint once installed.
Yes — a deposit against an approved drawing is normal; production should not begin before the drawing is signed off.
