Claire Choisne surprises us once again by using an atypical material, the Cofalit®.
Without prejudging it, she mixes a recycled material with diamonds. Because cofalit® is the result of the recycling of industrial waste! Often used as a roadbed filler, this «last material» becomes valuable here. In order to draw attention to sustainable development, the House BOUCHERON Reaffirms here its will.
In other words, this approach leads us to open up our view of precious objects a little more. In the same way as the alchemist transforms lead into gold, here the jeweler re-values what no longer has any use.
There is no doubt that for this capsule collection, the codes of jewelry are challenged. Thus, the artisans of the Maison have combined their expertise to elevate the jewelry tradition by dressing the icon with Cofalit® Jack de Boucheron. Precious For The Future, l‘commitment of BOUCHERON, is also a constant innovation, relying on the technical advances of its time to propose bold jewelry that makes sense.
In fact, Cofalit® is the most recycled product there is. According to the codes of jewelry design, the Cofalit is faceted with boldness and elegance for this capsule collection.
