Authentication and anti-counterfeiting

No piece is listed before it has been authenticated in Paris. Our process combines machine analysis with a manual review by specialists, and each order ships with a certificate of authenticity.

The three steps

First, machine analysis of the material grain, hardware and stitching. Second, a manual review by a specialist of the maison concerned, covering serials, date codes, hallmarks and movement where relevant. Third, a written condition report published on the listing.

Our guarantee

Any piece proven inauthentic is refunded in full. Counterfeit items submitted for sale are refused, reported and never resold.
