M. Vuillermoz was a French designer active in the 1960s, primarily known for a striking polyhedral bar cabinet, often referred to as the “Diamond” bar.

Published by the French editor Dambrine, the piece reflects the modernist aesthetic of the period: a faceted geometric structure in rosewood, accented with brass, set on casters and opening through multiple flaps to reveal a fully fitted interior.

Both sculptural and functional, this bar remains the most emblematic work associated with Vuillermoz today.
