This ring by Ariana Boussard-Reifel is very cool. They note, “The Ranunculus Ring blooms like a night flower, unfurling across your knuckle. It is the latest evolution of our classic Raissa style.  This collection of rings emulates blooming petals. Ranunculus is gorgeous worn alone or with companion rings. This piece is part of Dark Flowers,  a collaboration made with Jason Wu. The capsule pairs botanical elements with shapes inspired by Meso-American Indigenous design all treated with our signature bold sculptural style. The gestural shapes empower and remind us that even in darkness beautiful flowers bloom.”

I believe this is made with brass, and is priced at USD$195.
