BOUCHERON, PRECIOUS SAND

The new capsule collection, dedicated to the icon Quatre, is part of this lineage, where the material becomes both a subject of reflection and an aesthetic vehicle. This time, black sand is the unexpected guest in a dialogue with yellow gold.

Since its foundation in 1858, Boucheron He has continued to question the concept of value in jewelry. The new capsule collection, dedicated to the icon Four, is part of this lineage, where matter becomes as much a subject of reflection as an aesthetic vehicle. This time, the black sand is the unexpected guest in a dialogue with the yellow gold.

Under the direction of Claire Choisne, creative director, the house has resorted to a technology rarely associated with the luxury world: 3D sand printing. Usually used in the automotive or aerospace industries, this method involves bonding the grains in successive layers, giving them strength and texture. This innovative process, applied to the graphic rigour of the Four, It opens up a new field between craftsmanship and scientific innovation.

The result takes the form of seven pieces, cufflinks and brooches, which can be superimposed or individualized. The Paris motif unfolds here in XXL proportions, with the sand contrasting the dense light of the gold. Each bracelet is designed as a fragment of contemporary architecture, multiplying sharp edges and play of material. The whole forms a visual language where the mineral harshness of the sand confronts the precious warmth of the metal.

By transposing a fragile and moving material into the realm of jewelry permanence, Boucheron continues a reflection begun in 2015 with the necklace of Blue of Jodhpur which had already imprisoned a desert in a jewelry box. More recently, successive capsule collections have experimented with denim, aluminum or glass, each time to question the boundary between the precious and the unexpected. The black sand of this capsule is the new stage: a symbol of passage, fixed by technique and magnified by the creative gesture.
