A highly detailed bicycle brooch worked in 18-karat yellow gold, set throughout with round brilliant-cut diamonds in pavé and bead settings along both wheel rims, the top tube, handlebar grips, saddle, and chain guard, totaling an estimated 2.5 carats. The spoked wheels are fully articulated and rotate freely, as does the front handle bars, demonstrating a level of mechanical engineering rarely encountered in figural jewelry of this scale. A round ruby cabochon is set at the rear of the frame, functioning as a taillight accent and providing the sole point of color against the otherwise white and gold palette. A small gold heart is mounted at the seat tube junction, a detail that reads as a maker's or workshop signature motif.
The construction throughout is three-dimensional and open-worked, with individually fabricated wire spokes radiating from hub to rim on both wheels, the chain rendered link by link, and the handlebars properly formed with drop curves. The depth of the piece, visible in the side profiles, confirms fully sculptural rather than flat fabrication. A 18k stamp is visible.
