Authenticity Guarantee

Our Authenticity Guarantee

Every piece. Every time. No exceptions.

At UN ATELIER, authenticity is not a promise — it is our standard. Every item in our collection undergoes a rigorous, multi-step authentication process conducted by our team of luxury goods specialists before it is offered for sale. We exist to give discerning clients absolute confidence in every purchase.


Our Authentication Process

01 — Initial Sourcing Review

Every item is carefully sourced and subjected to a preliminary review before it enters our authentication pipeline. Items with incomplete provenance or inconsistent documentation are rejected at this stage.

02 — Expert Physical Inspection

Our specialists examine each piece in detail — hardware, stitching, lining, stamps, date codes, serial numbers, materials, and construction — against verified reference standards for each brand and collection.

03 — Provenance & Documentation

Where available, we verify accompanying documentation including original receipts, dust bags, boxes, and care booklets. All documentation is photographed and archived as part of the item's record.

04 — Certificate of Authenticity

Every item sold by UN ATELIER is accompanied by a Certificate of Authenticity issued by our team. This certificate documents the item's key identifiers and confirms it has passed our full authentication review.


Our Guarantee to You

In the unlikely event that an item you receive is determined to be inauthentic, we will issue a full refund upon return of the item — no questions asked. Your confidence is our commitment.
