Two-Tone Diamond Swirl Engagement Ring CAD Design with Pavé Split Shank

This bespoke engagement ring pairs warm rose gold with a flowing white gold accent to create a graceful, ribbon-like silhouette around a brilliant round center diamond. The pavé-set split shank adds layered sparkle and gives the piece a refined contemporary character, while the overall form feels elegant, fluid, and sculptural. Developed through custom jewelry CAD design and 3D jewelry modeling, this piece is a strong example of luxury engagement ring design for clients seeking a modern two-tone diamond ring with distinctive movement and premium fine jewelry detailing.
