Rick Owens x Christiane Billet pre-Hunrod limited Bronze Ring

Numbered bronze ring by Christiane Billet for Rick Owens from around 2000. Apparently only 8 of these somewhat obscure rings were made by the artist Christiane Billet at request of Michèle Lamy who was a fan of Billet's raw bronze sculptures. Billet has since gone back to making sculptures. From what I can make out from the engravings, this ring seems to be engraved with the number 6. On the last picture, you can see Michèle Lamy wearing at least one of her rings (second one from right to left) and if I'm not mistaken, there's also one of Billet's bronze bracelets lying on the coffee table next to her.

Size 56, measurements can be seen in the pictures.
