This refined princess-cut diamond ring CAD model presents a sleek and elegant engagement ring design featuring a raised central stone supported by a structured prong setting and accent stones along the shank. The clean band profile combined with subtle side diamonds delivers a timeless luxury look suitable for both modern and classic jewellery collections.

The design ensures maximum light exposure to the center stone while maintaining secure stone placement for daily wear durability. Side stones enhance brilliance without overpowering the central gemstone, resulting in a balanced and premium aesthetic.

Carefully optimized for jewellery manufacturing, the model features casting-friendly geometry, proper metal thickness, and smooth surfaces for efficient polishing and finishing. The under-gallery and prong architecture are engineered to maintain strength while minimizing excess metal weight.

This model works well for engagement rings, bridal collections, and fine jewellery product lines, and can be easily customized for different metal types, stone sizes, and ring sizes.
