Particularly active in the 1970s for Van Cleef & Arpels, Atelier JANCA also produced jewelry for Fred and Piaget. Its creations are distinguished by the use of decorative stones in a variety of colors, such as chrysoprase, tiger-eye quartz, coral, onyx or turquoise, and by its work on metal textures. Animal subjects occupy an important place in his creations. The emblematic "Papillons" from the Van Cleef & Arpels Boutique - whose model is similar to ours - were notably made by Atelier Janca.
