The Story

Made by hand, when the continental ateliers still set everything by hand.

The provenance for this piece is recorded against its piece-level documentation file. Approved partners can view full hallmark identification, period-appropriate setting techniques, condition history, and prior-ownership notes alongside the piece.

For the showroom conversation, the short version is the one the case card carries: era, atelier or designer, and what makes the piece worth a vitrine. The long version is for the client who's asking the right questions.
