This cushion cut three-stone diamond ring model combines soft curves with structured elegance, creating a timeless engagement design. The center cushion-cut stone is secured in a refined four-prong setting that enhances brilliance while maintaining strong stone support. Its rounded corners and larger facets give a romantic appearance with exceptional light reflection.

On both sides of the center stone, tapered baguette diamonds are precisely positioned to create a sleek and sophisticated transition into the band. The clean lines of the baguette stones complement the soft cushion shape, resulting in a balanced and luxurious look.

The shank is designed with practical thickness and a smooth inner band for comfortable daily wear. The gallery structure provides stability for casting and secure stone setting, ensuring durability throughout the manufacturing process.

This CAD model is professionally prepared for jewellery production. Stone seats, prongs, spacing, and metal proportions are optimized for casting, polishing, and precise stone mounting. The geometry is clean and manufacturing-friendly, making it suitable for high-end custom jewellery and bridal collections.

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