Geometric Brooch Tech Pack

I am developing a statement line of gold- and silver-based geometric brooches and need a seasoned jewelry designer who can translate my ideas into a full production-ready tech pack. The collection will feature large pieces—each larger than 4 cm—built around bold, intricate geometry. While I have no fixed preference for a single shape, I’m drawn to complex outlines that are vintage. Your creativity in pushing geometric boundaries is welcome, provided the final forms remain manufacturable in precious metals.

What I need from you
• Concept sketches or initial CAD renders that explore several complex geometric silhouettes.
• Finalised CAD files (Rhino, Matrix, or comparable software) with front, side and isometric views.
• Precise dimensions, weight estimates and tolerance notes suitable for both gold and silver casting.
• Pin mechanism detailing—including clasp type, placement and assembly instructions—to guarantee secure wear on a piece 4 cm and above.
• Finish specifications (e.g., high polish, satin, mixed textures) and any optional gemstone or enamel accents if you recommend them.
• A concise manufacturing instruction sheet covering metal purity, casting method, surface treatment and QC checkpoints.

Acceptance criteria
The tech pack must be clear enough for a third-party workshop to quote and produce a first prototype without further clarification. All files should be delivered in editable CAD format plus PDF line drawings.

If you have a portfolio of previous geometric or sculptural jewelry, please share it so I can gauge stylistic alignment. I’m ready to start immediately and look forward to turning these modern shapes into wearable art together.
