Vintage Black Onyx and Yellow Gold Jewelry Set

This jewelry suite consists of a matching pendant necklace and stud earrings. Each piece features a cabochon-cut, oval-shaped black gemstone, likely black onyx, characterized by its deep, opaque saturation and smooth, polished surface that reflects light with a soft luster. The stones are secured in four-prong settings crafted from yellow gold. The pendant is suspended by a tapered bail from a fine yellow gold curb or wheat-style chain, which exhibits a delicate yet durable link construction. The matching earrings are petite studs mirroring the design of the larger pendant stone. The aesthetics suggest a mid-to-late 20th-century vintage style, often associated with elegant, everyday formal wear. In terms of condition, the metal appears to be in good vintage state with a mild patina and light surface scratches consistent with careful previous wear. No significant abrasions, chips, or surface dullness are visible on the gemstones. The prongs appear securely seated, though a professional inspection would be needed to confirm the gold karat weight (typically 10k or 14k for this style) and to verify if the stones are natural onyx or a glass/resin simulant.
