Classic Engagement Ring CAD Duplication

A time-sensitive duplication of a simple, classic engagement ring is ready to move forward. The existing concept is fully defined— what is missing is a clean CAD that faithfully captures the subtle curves my previous overseas partners could not translate.

Core specs
• Centre stone: 6.5 mm round
• Metal: 14–18 k yellow gold (final karat will be confirmed)
• Shank: 5 mm wide at the base, 1.4 mm thick, comfort-fit interior
• Finger size: US 7
I also have a video of the ring but not sure how to upload it

The model must feel elegant yet understated, with every profile flowing smoothly from head to shank. Precision on symmetry and inside curvature is critical; the slightest flat spot will be rejected.

Timeline
– First CAD draft: within 48 hours of project start
– Revisions: turned around within a further 48 hours

Accepted software: Rhino, MatrixGold, or comparable jewellery-grade CAD capable of outputting watertight manufacturing files.

Deliverables
• Final native 3dm file
• Production-ready STL (high-res, manifold)
• One set of viewport screenshots for visual confirmation before sign-off

I will supply any additional dimensions or reference photos immediately after awarding. High-resolution renders are a bonus but not mandatory.

Accuracy, punctual communication, and respect for the curve details will secure prompt approval and future work on upcoming designs.
