Diamond Heart Lock Necklace

The push lock charm is where the design begins. Choose from geometric shapes — hexagon, oval, rectangle, rhombus, triangle, round — or distinctive forms like padlocks and paper clips. Each charm is 14K gold, and many carry diamond detail along the perimeter, scattered across the surface, or set in clusters. The push lock closure is built into every charm, opening with a press to attach or detach from a chain without tools or assistance.

The included split chain is sized to the charm and opens at the push lock for easy on and off. Beyond the included chain, every push lock charm works with thin gold chains in any style — cable, paper clip, curb, or rope — and at any length from choker to layered long. Shorter chains (16–18") wear the charm high near the collarbone. Longer chains (20–24") let the charm hang lower for layering or solo wear. Multiple chain lengths build the foundation of a flexible collection.

The push lock holds more than one charm. Layer multiple push locks with multiple charms on the same chain for stacked geometric character. Mix diamond push locks with plain gold for visual variation. Add diamonds, initials, birthstones, or anniversary shapes that mark specific moments. The chain becomes the constant; the charms tell the story. You don't have to commit to a single look — swap charms in and out as the day or the year changes.

The push lock necklace is part of The Lisa Robin Edit — pieces curated for lifetime wear and multi-way styling. Build your collection one push lock and one chain at a time. Wear a single push lock on a simple gold chain for daily detail, layer three push locks across two chain lengths for evening, or pair a push lock with other Lisa Robin necklaces — solitaires, lariats, chains — for a layered look that's uniquely yours. The pieces work together because they're designed to.
