This radiant cut three-stone diamond ring model combines strong geometry with brilliant sparkle, creating a refined and luxurious engagement design. The center radiant-cut stone is secured in a classic four-prong setting, carefully positioned to enhance light performance while maintaining structural strength. Its trimmed corners and faceted brilliance provide a perfect balance between the elegance of an emerald cut and the fire of a round brilliant.

On both sides of the center stone, tapered baguette diamonds are precisely aligned to create a smooth transition into the band. The linear side stones enhance the elongated look of the radiant cut, adding sophistication and symmetry to the overall design.

The gallery structure is engineered for durability and secure stone placement, ensuring stable casting and reliable setting. The shank features a clean profile with practical thickness and a smooth inner band for comfortable daily wear.

This CAD model is professionally prepared for jewellery manufacturing. Stone seats, prong placement, spacing, and metal thickness are optimized for casting, finishing, and accurate stone setting. The geometry is clean and production-ready, making it ideal for high-end engagement rings and fine jewellery collections.

The design performs beautifully in yellow gold, white gold, rose gold, or platinum.
