Sapphire Eternity Ring

Model a classic eternity ring where eleven oval sapphires circle the band over a continuous diamond channel. The design is built on precision curve work: reference lines measured to the hundredth, a blended profile fitted at 0.1 tolerance, and a measured 2.146 mm offset — all multiplied around the ring with Quick Polar Array.

The band itself comes from a Classic shank carved with arc-based cutouts, a 0.25 mm channel offset for the diamonds, and a hollowing pass that respects every girdle. Manual pavé fills the channel, Dynamic Prongs secure each stone, and cutters plus a final boolean finish the model — with an optional 0.15 mm fillet pass for softer renders.
