Elegant Key and Heart Lock Charm Necklace
$4.00
The Key and Heart Lock Charm Necklace 3D Model is a coordinated dual-piece set featuring a ~0.006 CT diamond key and 3D heart lock, optimized for seamless jewelry production.
Description
Two pieces. One idea. And a design that sells itself the moment it’s understood.
The Key and Heart Lock Charm Necklace 3D Model is built around a simple narrative: connection. A key that fits. A lock that waits. And a form language that makes both feel inevitable.
This dual-piece set is engineered for jewelers who want versatility without complexity.
The key pendant is stripped to its essentials—an oval open frame, clean shaft, and a single precision detail:
a 1.2mm round diamond (~0.006 CT) set at the key tooth. It’s not decoration. It’s punctuation.
The heart lock charm answers it with volume. A fully sculpted 3D puffy heart, polished to reflect light like a mirror. At its center, a subtle keyhole engraving completes the story—quiet, intentional, unmistakable.
Together, they create a modular design system:
- Wear separately
- Combine into a narrative piece
- Adapt across collections

This is more than a pendant. It’s a system designed for production efficiency and emotional resonance—two things that rarely meet this cleanly.
Designing matching jewelry sets from scratch takes time, coordination, and repeated revisions.
Misaligned proportions, inconsistent styling, and extra modeling hours slow down production and complicate your workflow.
The Key and Heart Lock Charm Necklace 3D Model provides a fully coordinated, production-ready set—so you can skip the back-and-forth and move straight to manufacturing.
