Luxury Diamond Key Pendant 3D Model

Description

A symbol everyone understands.
A form your workshop can build with confidence.

The Diamond Key Pendant transforms a timeless European-inspired key into a production-ready jewelry CAD model. A pavé diamond halo frames a delicate six-petal floral cutout, giving the pendant both classical romance and modern restraint. It reads vintage at first glance—then reveals contemporary clarity in its structure and proportions.

Built for jewelers and professional designers, this model is engineered for efficient casting, predictable stone setting, and consistent finishing—so your bench work stays focused on craftsmanship, not correction.

Dimensions & Proportions

• Total length: 38.68mm

• Key head diameter: 13.17mm

• Key head thickness: 3.83mm

• Overall form: Vertical key silhouette with balanced proportions

The scale creates presence without excess metal weight, suitable for everyday-wear collections and boutique lines.

Structural Design

• Double-Layer Key Head:

  • Outer halo: pavé-set diamond ring

  • Inner layer: six-petal floral openwork for depth and lightness

Prepared for casting, setting, and rapid prototyping workflows.

Designing a refined Diamond Key Pendant from zero means managing pavé spacing, layered geometry, and setting tolerances—time-consuming and repetitive.

Each revision slows sampling, increases labor cost, and delays your production schedule.

This ready-built Diamond Key Pendant model removes the CAD bottleneck—so you move directly from file to finished piece with confidence.
