Great jewelry often begins with a symbol.And few symbols carry as much history as the fleur-de-lis.

The Fleur de Lis Diamond Key Pendant Necklace 3D jewelry model transforms this timeless emblem into an intricate key design inspired by French Art Nouveau elegance and Baroque ornamental curves. The result is a pendant that feels less like an accessory and more like a miniature piece of royal architecture—elegant, expressive, and unmistakably distinctive.

For jewelers and jewelry designers, the Fleur de Lis Diamond Key Pendant Necklace offers something rare: a highly detailed CAD design that captures artistic complexity while remaining ready for production.

At the top, a triangular openwork diamond bail introduces the pendant with refined symmetry. Its edges are pavé-set with round brilliant diamonds, creating a smooth transition into the dramatic key head.

The Fleur-de-Lis CrownThe centerpiece of the pendant is a majestic three-petal Fleur-de-lis crown. The central petal rises proudly, tapering into a delicate teardrop-shaped openwork detail that adds lightness and elegance.

On both sides, the petals are structured with radiating baguette diamonds, arranged like beams of light spreading outward. These baguette stones provide a sharp geometric brilliance that contrasts beautifully with the softer sparkle of the surrounding round diamonds.

The petal surfaces and contours are meticulously set with round brilliant diamonds, forming a luminous outline that enhances the sculptural depth of the crown. Beneath the center petal lies a subtle circular openwork accent, adding balance and visual breathing space within the composition.

Extending from the crown are symmetrical S-shaped scroll arms, inspired by Baroque ornamental motifs. Each scroll finishes with a round diamond accent, giving the pendant a graceful sense of movement and artistry.

Structural FlowBelow the crown sits a horizontal baguette diamond band, forming a refined visual break between the decorative head and the key shaft. This architectural detail strengthens the pendant’s structure while adding additional sparkle.

The key shaft is a polished cylindrical column adorned with three vertical rows of pavé-set round diamonds, creating a rhythmic brilliance that runs the entire length of the pendant.

Near the base, another baguette diamond ring mirrors the upper band, reinforcing the symmetrical elegance of the design.

The pendant finishes with a distinctive single-sided scroll key bit, shaped like a flowing ornamental hook. This artistic flourish gives the piece a romantic character while maintaining the classic symbolism of a key.

Built for Jewelry ProfessionalsThe Fleur de Lis Diamond Key Pendant Necklace is designed with professional jewelry production in mind. Every stone seat, surface curve, and ornamental transition has already been engineered within the CAD structure.

Instead of spending hours constructing pavé layouts or balancing decorative elements, jewelers can move directly from design to rendering, prototyping, and manufacturing.

Because creativity should drive the design process—not technical bottlenecks.
