This striking piece is by Cheryl Eve Acosta. Her site notes, “Our crescent tide bangle is perfect for everyday wear; a minimal forged and hammered design with a touch of glass enamel. Inspired by the lunar phase and the water tides, each handmade piece made by the artist is available in black or white over copper. Custom colors, metals, and textures are available. The black color can come non textured and white can be textured.”

This is priced at USD$450.
