Modern-Vintage Brooch 3D Model

I’d like a detailed 3D model of a brooch that blends vintage elegance with a clean modern twist. The final piece will be cast in silver, so dimensions and tolerances need to respect standard jewellery manufacturing practices and stone-setting clearances if you choose to add gems. I also have some designs in my mind that I sketch them roughly and I need a 3-D design on them.

I’ll need:
• A production-ready CAD file (STL or STEP) plus the original editable file from your preferred software—Rhino, MatrixGold, Blender, ZBrush or similar.
• Two or three high-quality renders showing the brooch from different angles to illustrate surface finish and scale.

Please keep the overall look balanced: classic scrollwork or filigree references from vintage design, paired with subtle, contemporary geometry so the piece feels current rather than purely antique. Shiny silver is the only material requirement; no gold or platinum variations are necessary.

Let me know your proposed workflow, which software you plan to use, and an estimated turnaround time. I’ll review the initial concept in low-res, suggest any tweaks, then we can lock the model for final export.
