Description

Round diamonds set in 18k gold, this necklace carries the kind of clean, centered presence that reads well at any neckline — and the adjustable chain means the drop sits exactly where it should. As a long-tail pick within the broader 18k gold diamond necklace with adjustable chain category, the piece earns its place through construction, not decoration.

It layers cleanly over lighter chains or wears alone against a décolletage, the diamond catching light without competing with the setting. Explore the women's diamond necklace case to compare stones, settings, and chain lengths across the full collection.
