Gold Emerald Necklace CAD Design

I am commissioning a production-ready CAD model for a one-of-a-kind, high-end necklace that will ultimately be fabricated in gold for a private client. The brief centres on elegance and wearability while showcasing emerald as the hero stone; accent gems can be suggested if they enhance the design, but emerald must remain the focal point.

The core deliverables I will need from you are:
• A fully parametric CAD file (Rhino, MatrixGold, or a comparable jewellery-grade platform) suitable for direct CAM or lost-wax casting.
• High-resolution, photorealistic renders from multiple angles to show the client.
• STL (and, if your software allows, 3DM) exports ready for printing, with correct tolerances and sprue considerations.
• A concise specification sheet noting metal weight estimates and stone sizes/counts.

The project ends once the files have been test-printed virtually and pass basic manufacturability checks. Two rounds of minor revisions are included so we can fine-tune proportions or stone settings after the first client review. Your creative input on clasp style, chain articulation and how the emerald is presented will be highly valued, provided the final piece remains both luxurious and practical to wear.
