A rigorous authentication process
Authenticity is much more than a promise: it is at the very core of our business. Every pre-owned luxury item we offer is physically authenticated before being listed for sale, ensuring you can purchase with complete peace of mind.
Why trust Cornerluxe?
The luxury resale market is booming… and so is counterfeiting. Our role is to guarantee the traceability, quality and legitimacy of every item.
Our authentication experts have more than 20 years of experience in the resale of luxury goods, allowing us to quickly detect even the most subtle counterfeits.
Cornerluxe authenticity certificate included
Every item sold comes with a CORNERLUXE authenticity certificate, reflecting our commitment. Our physical boutiques in Paris provide an additional guarantee of trust and transparency.

High-level technical expertise for every item
Our specialists thoroughly analyze:
- The quality of stitching and finishes
- The materials used
- Signatures, logos and copyrights
- Date codes and RFID chips
- The overall consistency of the piece
- Any potential irregularities
When necessary, we call upon external specialists: gemologists, watchmakers or vintage experts.
We also use advanced technologies such as Entrupy©, which uses artificial intelligence to detect counterfeits with more than 99.1% reliability.
