This emerald cut three-stone diamond ring model reflects refined elegance and clean architectural beauty. The center emerald-cut stone is secured in a classic four-prong setting, designed to highlight its step-cut faceting and elongated rectangular shape. The large open table of the emerald cut creates a sophisticated hall-of-mirrors effect, offering timeless appeal.

On each side of the center stone, tapered baguette diamonds are precisely positioned to complement the strong linear geometry of the emerald cut. The seamless transition from the side stones into the band enhances the ring’s sleek and balanced appearance.

The gallery structure is engineered for durability and secure stone placement while maintaining a light and elegant profile. The shank is proportioned for comfortable daily wear, featuring a smooth inner band and practical thickness suitable for long-term use.

This CAD model is professionally prepared for jewellery manufacturing. Stone seats, prongs, spacing, and metal thickness are optimized for casting, finishing, and accurate stone setting. The geometry is clean and production-friendly, 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.
