Gold Engagement Ring CAD Design

I want a detailed 3D CAD model for a gold engagement ring that will be ready for manufacturing and marketing visuals. The concept is sketched but still flexible, so I will share reference photos and measurements once we start. Your job is to translate those references into an accurate, stone-ready file with clean geometry and realistic renders that highlight the setting and metal finish.

Please work in Rhino, Matrix, or similar professional jewellery software so the output can be provided in STL for printing and a native editable file (3DM or equivalent) for any future adjustments. High-resolution PNG or JPEG renders with at least two lighting setups are also needed.

Acceptance criteria:
• Final CAD meets the given finger size, stone dimensions, and prong layout.
• All edges are filleted appropriately for casting in gold.
• STL passes Magics/netfabb checks without repair.
• Renders clearly show top, side, and perspective views with accurate gold material and diamond refraction.

If you have previous engagement ring examples, sending a few images or a quick link will speed up approval. I’m ready to begin as soon as I see a solid portfolio piece that matches this style.
