Jeweler Ben Baller believes he’s created the piece “of the decade” for Kid Cudi.

Kid Cudi appeared at the Met Gala with the chain, which is valued at nearly $2 million. The $1.6 million chain is a play on artist KAWS’ famous “Holiday Space” astronaut figure. In an Instagram post, Ben Baller described working with Kid Cudi and KAWS to complete the piece, which has been titled, “Space.”
