This octagon-shaped diamond stud earrings CAD design is developed for high-end jewellery manufacturing with a strong focus on precision, durability, and visual balance. The design features a prominent emerald-cut center stone framed by a refined double halo arrangement, enhancing brilliance while preserving a clean geometric aesthetic.

The structured octagonal outline gives the earrings a modern luxury appeal, making them suitable for premium and bridal jewellery collections. Each halo layer is carefully spaced to ensure proper stone setting tolerance, allowing smooth setting and secure placement during production. The prong structure is optimized to maintain stone safety without interfering with light performance.

The backside construction includes intelligently placed cut-outs to reduce overall metal weight while maintaining structural integrity. This helps achieve cost efficiency in gold usage without compromising strength. The post and screw-back system is engineered for long-term wear, ensuring comfort, balance, and stability once worn.

All surfaces are designed with smooth transitions and correct wall thickness, allowing flawless casting, polishing, and finishing. The model is fully compatible with professional jewellery manufacturing workflows and can be produced in yellow gold, white gold, rose gold, or platinum as required.

This CAD model is suitable for both custom jewellery orders and serial production, making it a versatile addition to any professional jewellery design library.
