Photorealistic Jewelry 3D Modeling

I need detailed, photorealistic 3D models of diamond pieces set in both gold and silver. These models will be used across e-commerce product pages, social ads, and short promotional videos, so surface accuracy, realistic gemstones, and clean topology are critical.

Here is what I expect:
• A fully-textured, render-ready file for each design (preferred formats: .blend, .fbx, or .obj with separate texture maps).
• High-resolution still renders on transparent and lifestyle backgrounds.
• Optional: a 5–10 sec turntable or hero shot clip per item that I can drop straight into Meta or TikTok ads.

I already have reference sketches and dimensions ready to share once we start. If you rely on tools such as Blender, Rhinoceros, ZBrush, KeyShot, or similar, please mention that so I can slot the files into my existing pipeline.

Acceptance criteria
1. Gem cuts, prong settings, and metal finishes must match the references to the millimeter.
2. Renders should hold up at 4K resolution without visible noise or fireflies.
3. All files must open without missing textures or modifiers.

Send a link to two or three previous jewelry models—especially diamond work—so I can quickly gauge style compatibility. Turnaround on the first piece is one week; additional models will follow if we work well together.
