Soho 18 Karat White Gold Pave Diamond and Black Onyx Swirl Pin

A striking swirl motif pairs luminous pavé-set diamonds with deep black onyx for high-contrast brilliance in 18 karat white gold. The curvilinear form reads clean and modern, with the diamond ribbon tightly pavé-set for a continuous, scintillating surface against the glossy onyx arc. Crafted in 18k (750) white gold, the pin showcases precise pavé work—small diamonds closely set with fine bead prongs to maximize light return—framed by the polished metal’s cool tone. The black onyx element presents a smooth, high-luster finish that sharpens the graphic silhouette. A refined, sculptural design that emphasizes contrast, contour, and meticulous setting detail.
