This Marquise Cut Halo Engagement Ring CAD model is designed to enhance the elongated elegance and brilliance of a marquise center stone. The center diamond is secured with precision claw prongs, including reinforced prongs at the pointed tips to provide maximum protection while maintaining a refined and delicate appearance.

A finely structured halo surrounds the marquise stone, following its tapered silhouette with perfect symmetry. The halo enhances finger coverage and amplifies brilliance without overpowering the center stone. The proportions are carefully balanced to maintain a sleek and luxurious profile.

The shank features a half pavé diamond setting, adding continuous sparkle along the upper portion of the band. Each pavé seat is precisely spaced to ensure secure stone setting and smooth finishing during manufacturing.

The elevated gallery allows optimal light entry beneath the center stone, increasing brilliance and fire. The under-structure is engineered with proper thickness and support to ensure durability, casting reliability, and long-term wear comfort.

This model is developed with clean geometry, accurate stone seats, and production-ready tolerances, making it ideal for fine jewellery manufacturing, custom bridal collections, and professional 3D printing workflows.
