Art Deco Style Black Onyx and Marcasite Sterling Silver Pendant

This is a vintage-inspired pendant featuring a large, polished oval cabochon of black onyx held within a silver-toned metal setting, likely sterling silver. The piece is approximately 3.5 to 4 centimeters in length. The primary design element is an elegant, swirling scroll motif that serves as the decorative bail, extending down the front of the gemstone. This scroll is intricately pave-set with numerous small, faceted marcasite stones and finished with delicate milgrain edging, a hallmark of Art Deco and Art Nouveau Revival styles. A smaller, matching decorative cap is positioned at the base of the onyx bead, providing visual balance in a 'drop' silhouette. The black onyx displays a high-gloss, reflective surface with no visible deep scratching or chipping, while the marcasite stones appear to be mostly intact, retaining their characteristic metallic luster. The metal shows a slight dark patina consistent with aged silver, which enhances the detail of the grain work. Based on the construction and styling, this piece likely dates from the late 20th century, specifically the 1980s or 1990s, when Art Deco revival jewelry was highly popular. The craftsmanship is refined, with smooth transitions between the gemstone and the metal hardware.
