Jewelry CAD Designer – Create 3 Original Ring Models in Rhino / MatrixGold

I'm looking for an experienced jewelry CAD designer to create 3 original ring designs and high-quality CAD models for use in a jewelry technology project. The models will primarily be used for 3D visualization and virtual jewelry try-on testing, so accurate geometry and realistic details from all viewing angles—including the side/profile view—are important. The initial project will include: 1 classic diamond solitaire engagement ring in white gold 1 more detailed diamond engagement ring (such as a three-stone, halo, or another design with interesting side/profile geometry) 1 colored gemstone ring in yellow gold I'm open to providing design direction myself or having you propose the designs. Deliverables For each ring, I would like: Original editable CAD/source file (preferably Rhino/MatrixGold .3dm) STL OBJ FBX and/or GLB/glTF if available Stones and metal components separated where appropriate Accurate real-world dimensions and scale Clean geometry suitable for conversion and optimization for real-time web rendering Stone sizes and basic ring dimensions Original Work & Commercial Rights The designs must be original work created specifically for this project and must not copy or reproduce existing branded jewelry designs. I need full commercial rights to the completed designs and CAD files, including the ability to modify them and use them in software, websites, demonstrations, marketing materials, and commercial products. Please do not use third-party CAD models or other assets unless approved by me in advance. When applying Please include examples of jewelry CAD you have personally created, particularly rings, and let me know: Which software you primarily use (MatrixGold, Rhino, etc.) Your experience creating jewelry CAD Your estimated turnaround time for all 3 rings Whether you can provide the editable source CAD files in addition to exported 3D formats This is an initial project, with the possibility of additional jewelry CAD work in the future.
