This Round Solitaire Engagement Ring CAD model features a timeless and elegant design centered around a brilliant round-cut diamond. The classic round center stone is secured with evenly spaced prongs, offering maximum light exposure while ensuring strong and reliable stone protection.

The elevated head structure is engineered with vertical support pillars and an open gallery to enhance brilliance and maintain structural durability. Beneath the center stone, a hidden row of round accent diamonds is seamlessly integrated into the gallery. These hidden diamonds add subtle sparkle from side angles, creating a luxurious detail without altering the clean solitaire appearance from the top view.

The shank is designed with a smooth rounded profile and a comfort-fit interior, ensuring both elegance and everyday wearability. The transition between the shank and the head is reinforced for long-term durability during casting, stone setting, and polishing.

This model is optimized for jewellery manufacturing, featuring clean surfaces, precise prong alignment, accurate stone seats, and balanced proportions. The geometry is suitable for high-end casting in gold, platinum, and other precious metals. The structure allows for secure setting of natural or lab-grown diamonds.

Ideal for engagement collections, bridal lines, custom jewellery projects, and luxury solitaire variations that include hidden detailing for added sophistication.
