Every detail examined. Every piece respected.

Each item entrusted to Konesseur undergoes a meticulous evaluation process led by specialists with decades of experience across the world’s most prestigious Maisons.

From craftsmanship and materials to provenance and condition, nothing is left to chance.
Only pieces that meet our exacting standards are accepted and presented.

This is not authentication as a checkbox, it is authentication as a discipline.

Because every piece, and every seller, is different.

We offer multiple selling pathways, designed around your priorities:

Our team will advise you honestly on the best option for your item. Not the fastest, but the right one.

Your privacy is never compromised.

Luxury demands discretion.

Whether you choose to sell online, arrange a private appointment, or use our concierge service, your identity and information remain strictly confidential.

High-value pieces are handled with enhanced security protocols, and private client services are available for exceptional collections.

At Konesseur, trust is never visible, but always felt.

Presented to those who truly understand.

Your piece is introduced to a refined network of collectors, clients, and enthusiasts, both regionally and internationally.
