Four-Piece Jewelry Assortment Featuring Onyx and Amethyst

This jewelry assortment consists of four distinct pieces: a pendant necklace, a pair of stud earrings, and a loose teardrop pendant. The primary necklace features a large, rectangular emerald-cut black onyx stone set in a yellow gold-toned basket setting, suspended from a delicate Singapore-style chain. The matching stud earrings appear to feature circular, faceted black stones, likely onyx or spinel, held by four-prong settings with standard butterfly friction backs. Additionally, there is a small, loose pear-cut purple gemstone, likely amethyst, set in a minimalist yellow metal pendant mount. The metal appears to be at least 10k or 14k yellow gold based on the luster and color, though specific hallmarks are not visible in the provided image. The pieces reflect a classic, contemporary aesthetic typical of the late 20th century. The condition appears fair to good with minor surface scratches on the metal and stones consistent with gentle wear. The chain shows no visible kinks or breaks, and the settings appear structurally sound. The deep black hue of the primary set provides a sharp contrast against the gold-toned metal, suggesting a formal or semi-formal design intent.
