Gold Earrings 3D Model

I need a clean, production-ready 3D model of a pair of modern earrings that will be fabricated in gold. The silhouette should feel contemporary and refined; once complete, I will pass the file straight to my manufacturer, so accuracy and watertight geometry are essential. Please use whatever software you are most comfortable with—Rhino, MatrixGold, ZBrush, Blender, or similar—as long as you can deliver the native file plus a universal format (.STL or .OBJ) and a couple of high-resolution renders for quick visual review. When you respond, focus on your experience with jewelry modeling in precious metals. A short note pointing to comparable pieces you have executed and any relevant CAD/CAM knowledge is enough; no need for an elaborate proposal. I will make a fast decision once I see that you have successfully handled gold pieces before.
