A striking and sculptural 18K white gold geometric pin designed with bold contrasts of black onyx, pink coral, and brilliant diamonds. This highly stylized motif features six carved onyx elements flanking and framing nine polished coral accents, all arranged in a strong stepped and fan-shaped composition reminiscent of Egyptian Revival and Art Deco design vocabulary.

The surface is meticulously pavé-set with 117 round brilliant diamonds totaling approximately 1.05 carats, creating shimmering contrast against the richly colored gemstones. The carved forms, geometric symmetry, and clean architectural lines highlight the craftsmanship and dramatic visual language associated with Deco-inspired jewelry.

A standout statement piece that merges bold color, texture, and vintage glamour—perfect for collectors of unique gemstone creations.
