Presenting a refined Round Cut Hidden Halo Engagement Ring CAD model, designed with a modern elevated setting and elegant side details. This design features a brilliant round center stone secured with four strong prongs, lifted by a sculpted gallery that enhances light entry and brilliance.

A delicate hidden halo sits beneath the center stone, adding extra sparkle from the side view while maintaining a clean and classic top appearance. The shank is accented with a single row of precisely aligned round diamonds, delivering balanced brilliance without overpowering the center stone.

The open gallery structure ensures proper light performance and makes cleaning easier after stone setting. The model includes accurate stone seats, proper prong thickness, and optimized metal weight for safe casting and long-term durability.

The interior of the band is smooth and comfortable for everyday wear. The geometry is clean, manifold, and production-ready, suitable for professional jewellery manufacturing workflows.

This design works perfectly in yellow gold, white gold, rose gold, and platinum.
