This premium radiant-cut three-stone ring CAD model is crafted with exceptional precision, making it ideal for high-end jewellery production. The design features a bold radiant-cut center stone that captures maximum brilliance, paired with two elegant trapezoid side stones that enhance the ring’s symmetry and luxurious presence.

The center stone sits in a secure prong setting engineered for clean casting and perfect stone alignment. The side trapezoid diamonds are placed in a step-style arrangement that beautifully transitions into the shank, offering a refined balance between modern geometry and classic elegance. Each prong, seat, and gallery element is meticulously designed to ensure durability, light flow, and manufacturing accuracy.

The shank is smooth, comfortable, and crafted with ideal proportions for daily wear. The gallery structure is designed with open, supportive architecture to maintain strength while allowing maximum light penetration, giving the center radiant stone a striking, high-sparkle appearance.

This CAD model is optimized for casting, CNC machining, resizing, and customization. Its clean mesh and precise geometry make it suitable for professional jewellers, manufacturers, CAD designers, and online sellers who want a reliable, production-ready model for premium engagement rings. Ideal for catalog listings, custom orders, and high-end jewellery collections, this design delivers both technical efficiency and visual luxury.
