This Radiant Cut Three-Stone Diamond Ring 3D CAD model is professionally developed for jewellery manufacturers and custom engagement ring production. The design features a bold radiant-cut center stone secured with precision prongs, paired with two round brilliant side stones for enhanced brilliance and balanced symmetry.

The radiant cut combines the elegance of an emerald shape with the sparkle of a brilliant cut, making this design both modern and timeless. The elevated basket setting allows optimal light exposure while maintaining strong structural integrity for casting and long-term durability.

The prongs are carefully engineered to provide secure corner protection and proper stone seating. The round side stones are proportionally aligned to complement the center stone, creating a harmonious three-stone composition ideal for engagement and bridal collections.

The shank is designed with a smooth comfort-fit interior and appropriate metal thickness to ensure reliable casting in gold, white gold, rose gold, platinum, and other precious metals. Clean surfaces and precise detailing make this model production-ready and easy to modify.
