Petit Gateau Bangle — Swirl Tip

The spring hinge is the quiet genius of this black enamel bangle: press, slip, snap, and the Petit Gateau band sits flush on the wrist. Hand-poured enamel gives the black its lacquered depth, while a run of crystal keeps the surface lively.

Underneath, the piece is brass plated in rhodium, sized small at a 6.5-inch circumference, and finished nickel- and lead-free. It is a natural stacker — slide it beside gold bangles for contrast or repeat it in multiples — though it holds its own worn solo with a rolled cuff.
