This luxury layered diamond necklace CAD design is created with exceptional precision and premium craftsmanship, making it perfectly suitable for real jewellery manufacturing. The design features an elegant double-layered chain structure combined with beautifully spaced round diamond settings and a prominent center solitaire-style pendant.

The upper layer adds sparkle and balance with evenly placed round stone elements, while the lower layer highlights a bold central diamond setting that enhances the overall luxury appeal. This combination creates a timeless yet modern necklace design ideal for high-end jewellery collections.

Each stone setting is carefully engineered to ensure secure placement, smooth polishing, and flawless casting results. The CAD model is designed with clean geometry, accurate proportions, and production-ready structure, reducing post-processing work during manufacturing.

This design is ideal for gold, rose gold, white gold, silver, and platinum jewellery production and works perfectly for both daily luxury wear and special occasion jewellery.
