This vintage 18k yellow gold necklace features a symbolic heart, lock, and key charm trio, each set with pavé diamonds. The heart and lock showcase a coordinated pavé diamond layout, while the key is accented with a diamond-set stem. The gold link chain is designed with a graduated taper, transitioning from finer links near the clasp to larger ones near the central pendants. Measuring 17 inches in length and weighing 30.8 grams, the piece is stamped "A&G" and "18k." Circa 1990s–2000s, the necklace reflects a modern romantic design language, popular during that era.
