Single Stone Diamond Solitaire Necklace in Presentation Box

This item is a yellow-gold-toned necklace featuring a single round faceted stone, identified by the packaging labels as a genuine diamond. The pendant consists of a central stone secured in a circular bezel or illusion setting, which is integrated into a fine rope-style or box-link chain. The metal appears to be gold or gold-plated, though no specific hallmark is visible in the photograph to confirm karat weight. The necklace is housed in its original black velvet-lined presentation box with hinged lid. The interior lid is printed with 'GENUINE DIAMOND' in gold-colored capital letters. Two gold-toned oval stickers are present on the black velvet insert: one reads 'Genuine Diamond' and the other indicates a historical price point of '$100.00'. The style is characteristic of late 20th-century mass-market jewelry, likely manufactured around the 1980s or 1990s. The condition appears to be excellent and unused, with the original stickers still attached and the metal showing high luster without visible tarnish or chain kinks. The diamond appears small, likely under 0.10 carats, common for this type of promotional or entry-level fine jewelry.
