This luxury pendant 3D model features a bold square-shaped design rotated in a diamond orientation, centered around a brilliant round-cut ruby and framed by a refined halo of small diamonds. The strong geometric form combined with gemstone brilliance creates a striking and elegant pendant suitable for high-end jewelry collections.

The central ruby is securely elevated in a prong setting to maximize light exposure and visual impact, while the surrounding diamond halo enhances sparkle and depth. The layered structure adds dimension without excessive bulk, and the open side details improve airflow, reduce metal weight, and support clean casting and finishing. The bail is proportioned for durability and smooth compatibility with various chain styles.

This model is professionally designed for jewelry manufacturing and optimized for 3D printing and casting workflows.

It can be produced in gold or silver and adapted for different center stones such as ruby, emerald, sapphire, or diamond.
