Sterling Silver Abalone and Coral Composite Pendant with Quartz Necklace

This jewelry set includes a large, circular abalone shell pendant and a separate quartz point necklace. The primary pendant features a high-luster, iridescent mother-of-pearl or abalone shell disc, measuring approximately 40-50mm in diameter. It displays strong labradorescence with hues of silver, green, and blue. The shell is set in a bezel and topped with a round, cabochon-cut red coral or red stone accent, also held in a bezel. The metal components appear to be sterling silver or white metal with a visible bail at the top. The second piece is a raw, clear quartz crystal point capped in a heavy, decorative silver-toned metal casing featuring floral or Victorian-style relief patterns. This crystal pendant is suspended from a delicate cable chain. Both items exhibit minor surface scratches and a light patina consistent with moderate use. The craftsmanship of the shell pendant suggests a modern bohemian or artisan origin, while the crystal necklace has a more vintage-inspired aesthetic. There are no clearly visible hallmarks in the image, but the construction indicates high-quality costume or sterling-grade materials likely from the late 20th or early 21st century.
