This refined three-stone engagement ring features a striking princess cut center diamond complemented by round brilliant side stones. The sharp, geometric lines of the princess cut create a bold and modern focal point, while the round side diamonds add soft brilliance for a perfectly balanced composition.
The center stone is secured in a precise four-prong setting designed to protect the corners of the princess cut while maximizing light performance. Graduated round diamonds are elegantly arranged along both sides of the center, creating a smooth visual transition into the band. The side stones enhance the overall sparkle without overpowering the structured symmetry of the main stone.
An elevated gallery design allows optimal light entry beneath the center stone, improving brilliance while maintaining structural strength. The band features a smooth comfort-fit interior and carefully optimized metal thickness to ensure reliable casting and long-term durability.
This CAD model is production-ready with accurate stone seats, clean prong geometry, and well-balanced proportions. Available in yellow gold, white gold, and rose gold variations, it is ideal for bridal collections, luxury retail, and custom jewellery manufacturing.
