French 1960s Diamond Sea Urchin Cluster Ring, 18K Yellow Gold Wire Spike Design

Nineteen round brilliant diamonds cluster in an asymmetric cascade across one shoulder of this ring, set flush against a field of individually wire-formed gold spikes that radiate outward like a sea urchin's spines. Each spike is shaped and set by hand rather than cast as a single textured surface, giving the piece real dimension and movement — the gold catches light differently depending on the angle, shifting between matte shadow and bright glint across the spiked surface. The diamonds, F-G color and VS1 clarity, sit in a tight cluster rather than scattered evenly, concentrating the sparkle against the more muted gold texture around it. French hallmarks confirm its origin; this bold, sculptural, nature-inspired goldwork was a signature style of ambitious 1960s jewelry design, when houses on both sides of the Atlantic experimented with organic, textural forms as a departure from smoother mid-century lines.
