Among the standout pieces from the Or Bleu jewellery collection by Boucheron, is Eau Forte, a name derived from the French term for etching, used here as a pun since it literally translates to “strong water.” Inspired by the moment an ocean wave crashes, this piece references the etching technique used to create the bracelet’s relief. Boucheron’s artisans employed traditional etching to sculpt the gold, accentuating it with white lacquer and laser-printed black lacquer.
