Certified expertise with LegitGrails™

We use the professional version of LegitGrails™, an international luxury authentication solution recognized for its reliability and exceptional accuracy.
Based on a hybrid technology combining human expertise and artificial intelligence, LegitGrails achieves an accuracy rate of over 99%.

Each item is examined by several specialized authenticators, each an expert in specific brands (Chanel, Louis Vuitton, Hermès, Gucci, etc.).
LegitGrails teams are regularly trained and tested, and their verifications are based on a global database containing millions of authentic and counterfeit samples.

A technology recognized by professionals LegitGrails is a major player in the fight against counterfeiting in the fashion and luxury sector. The platform is used by over 100,000 stores, marketplaces and collectors worldwide and is recognized for its speed (results in less than 30 minutes) and reliability. In case of doubt during verification, several experts manually re-examine the item to guarantee a definitive and independent conclusion.

The certificate of authenticity

For each luxury item sold on labelleboutique.shop, a digital certificate of authenticity is systematically issued and included in the sales file.
This certificate, issued by LegitGrails, includes:

- A unique verification number, registrable online on the dedicated platform

- Detailed results of the analysis process

- Validation by an independent expert authenticator

N.B: Premium brand items (not considered to belong to the international luxury segment) are not accompanied by a certificate, although they are also visually inspected and evaluated according to our internal methodology.

What do we mean by "premium brands"? La Belle Boutique distinguishes two categories:

Luxury brands: historical houses with recognized heritage, enjoying strong value on the secondary market (e.g. Chanel, Hermès, Louis Vuitton, Dior, Gucci, Prada, etc.)

Premium brands: high-end, qualitative brands that do not fall within the international luxury segment (e.g. Sandro, Maje, The Kooples, Michael Kors, Coach...). This distinction allows us to ensure a level of service adapted to the nature and value of each product.

Our commitment

Every item sold by La Belle Boutique is authentic, verified and guaranteed.
By choosing our items, you benefit from:

• Internationally recognized expertise via LegitGrails™,
• A verifiable certificate for each luxury item,
