Jag Jewelry is the jewellery studio of Andreas Gmur, an artist-jeweller. In June 2021 Gmur made a sketch of a jewellery design inspired by La Fièvre d'Urbicande.
Andreas Gmur says “This comic book with its very architectural drawings fascinated me by its imagination and the series of “Les Cités obscures” from which this book comes seduced me by its references to the city of my childhood, Brussels.” 1)
“I have reproduced this structure of the original Urbicande cube, at the top of a ring. The cube imprisons a princess cut diamond that moves freely in this constrained space.” 2)
