Timed to the 25th anniversary reissue of Mariah Carey’s “Butterfly” album, the pop star has released a jewelry collection with Swiss luxury designer Chopard.

The “Happy Butterfly” collection includes 12 pieces featuring a butterfly crafted in “ethical rose and white gold” and is described in a release as having a “transparently openworked heart in which a dancing diamond nestles between two sapphire crystals.” Bangles, pendants, rings, and earrings are available from $6,330 to $23,500.

Chopard is also releasing a one-of-a-kind asymmetrical diamond-paved “Haute Joaillerie” set for its Mariah Carey collection, consisting of a necklace, a pair of earrings, and a ring crafted with round-cut and heart-shaped diamonds and set in 18k white gold, which the brand says is “certified ethical.” The pieces are co-signed by both the artist and Chopard co-president and artistic director Caroline Scheufele. Price available upon request.

Scheufele described the Chopard “Happy Butterfly” collection as a modern butterfly design paired with Chopard’s iconic “Happy Diamonds,” which are free-floating stones that move around as the wearer does. “Since Mariah has a personal passion for unique pieces, we knew we wanted to do a few one-of-a-kind creations that would be truly exceptional. This led to an extraordinary diamond suite,” Scheufele said.
