The Sophia ring features a radiant center diamond with delicate botanical-inspired accents, blending classic elegance with romantic charm.
The Diamond Heart Lock Necklace centers on a 14K yellow gold heart-shaped push lock charm with diamond accents. The push lock mechanism lets you swap charms or wear on different chains.
The Piece
The heart-shaped charm is approximately 25.25mm tall by 20.85mm wide in sustainably sourced 14K solid gold, with 1/5 carat total weight in natural mined diamonds (SI1 clarity, G-H color) set across the heart form. The push lock mechanism is built into the charm — opening with a press to attach to the included split chain or move to other chains. The heart shape reads sentimental; the push lock function adds the design flexibility.

Frequently Asked Questions
How do I care for this necklace?
Clean weekly with warm water and mild dish soap, using a soft toothbrush to reach detail around diamond settings or textured surfaces. Pat dry with a lint-free cloth. Remove the necklace before swimming, showering, or applying lotion, perfume, or sunscreen — these accelerate tarnish on gold and can dull diamond brilliance. Bring the piece for professional inspection and cleaning annually.
Can I layer this with other Lisa Robin necklaces?
Yes — this piece is part of The Lisa Robin Edit, designed for layering and multi-way styling. Pair it with a longer or shorter chain necklace at a different length to build dimension. Push lock charms, solitaire pendants, lariats, and plain chains all coordinate. The necklace works on its own as a daily piece or layered for evening; the design intent is flexibility.
How does the heart push lock work?
The heart-shaped charm has a push lock closure built into the design — pressing the side of the charm opens it, allowing the split chain to slide through or pendant to detach. Once closed, the chain runs securely through the charm. The mechanism makes the charm easy to swap onto different chains or layer with other push lock pieces in the Lisa Robin collection.
