Partnership Philosophy
Selected for alignment,
not for budget
Every partner of Jewels Basel is chosen because they belong in the room — not because they have written the largest cheque. The selection is curatorial: each partner must share the same relationship to quality, refinement, and the collector audience that defines the salon. A Jewels Basel partnership is a statement of cultural alignment, not a logo placement.
Venue & Hospitality
Grand Hotel
Les Trois Rois
Basel, Switzerland · Since 2018
With over 300 years of history on the banks of the Rhine, Les Trois Rois has been home to Jewels Basel since the very first edition. The hotel is not a venue — it is a collaborator. The Salle des Rois, designed by Herzog & de Meuron and inaugurated in 2025, opens for the 8th edition of Jewels Basel. The relationship between the event and the hotel is foundational.
