Single Stone Diamond Solitaire Pendant on a Fine Rope Chain

This piece of jewelry features a round brilliant-cut colorless stone, likely a natural diamond, suspended as a solitaire pendant. The stone is securely housed in a white metal four-prong setting, possibly 14k or 18k white gold or platinum, given the bright luster and sleek finish. The pendant is characterized by its minimalist 'rabbit ear' style bail which allows it to slide freely along the chain. The accompanying necklace is a fine-gauge rope chain, which features intertwined links that create a textured, shimmering effect when it catches the light. The overall aesthetic is contemporary and elegant, characteristic of late 20th-century to modern-day jewelry design. The stone appears to be approximately 0.15 to 0.25 carats based on its scale relative to the chain. While no hallmark or maker's mark is visible in the provided image, the craftsmanship of the setting is precise and symmetrical. The condition is excellent, showing no visible signs of tarnishing, metal fatigue, or loose prongs. The piece is presented in a black velvet-lined jewelry presentation box, suggesting a quality retail origin.
