This refined Emerald Cut Three Stone Engagement Ring CAD Design showcases a bold center stone paired with elegant trapezoid side diamonds, creating a balanced and sophisticated engagement ring style. The emerald-cut center diamond is secured in a strong prong setting that highlights its clean lines and step-cut brilliance.

The trapezoid side stones add width and symmetry, enhancing the visual presence of the ring while maintaining a timeless luxury appeal. The smooth band design ensures comfort and durability, keeping the focus on the architectural beauty of the three-stone arrangement.

This CAD model is designed specifically for professional jewellery manufacturing. Accurate proportions, well-defined stone seats, and a structurally sound shank make the design reliable for real production use. The model supports resizing and customization without affecting stone alignment.

Ideal for engagement rings and bridal collections, this design works beautifully across yellow gold, white gold, and rose gold variations and integrates seamlessly into casting and CNC workflows.
