Description
Some forms endure because they work.
Others endure because they mean something.
The Circle Key Necklace reimagines the classic key with a perfectly round halo—balanced, calm, and unmistakably refined. A pavé diamond circle frames a six-petal floral openwork center, uniting timeless elegance with modern minimalism. The result is a neo-classical pendant that feels familiar at first glance—and quietly contemporary on closer inspection.
Designed for professional jewelers and CAD designers, this Circle Key Necklace 3D model is production-ready. The geometry is clean, the pavé spacing is consistent, and the structure is optimized for casting and stone setting—so your workshop moves faster from concept to finished piece.
