This Princess Cut Solitaire Pavé Engagement Ring CAD model is designed for jewellery manufacturers seeking a clean, geometric bridal style with balanced proportions and production-ready precision. The sharp symmetry of the princess cut center stone delivers a bold, contemporary look while maintaining timeless engagement appeal.

The center stone is secured in a classic four-prong setting positioned precisely at the corners to protect the pointed edges of the princess cut. The prong structure is engineered for durability without adding unnecessary bulk, allowing maximum light exposure for brilliance and fire. The elevated head design ensures compatibility with straight wedding bands for a flush fit.

The shank features a refined half pavé arrangement of round accent stones along the upper band. The pavé diamonds enhance sparkle while maintaining structural integrity and comfortable wear. The lower portion of the shank remains solid and polished for long-term durability, resizing flexibility, and everyday comfort.

The internal construction is optimized for resin printing and casting. Accurate stone seats, balanced metal distribution, and appropriate wall thickness make this model suitable for professional jewellery production workflows. Clean geometry ensures smooth finishing and precise stone setting.

This design can be customized for different center stone sizes and is suitable for manufacturing in gold, platinum, silver, or other precious metals. Compatible with natural diamonds, lab-grown diamonds, and alternative gemstones.
