From CAD to Casting: The Complete Guide to Bespoke Jewelry in 2026

An inside look at the complete journey of bespoke jewelry creation — from initial digital design through precious metal casting to final presentation. Understanding this process helps you make informed decisions when commissioning custom pieces.

Phase 1: Concept & Digital Design (CAD)

Every bespoke jewelry piece begins as a digital concept. Computer-Aided Design (CAD) software allows designers to create precise three-dimensional models that can be viewed from every angle before any physical material is committed.

What happens in this phase:

• Initial consultation to understand your vision, preferences, and requirements
• Creation of detailed 3D renderings showing the piece from multiple perspectives
• Precise measurements for stone settings, band widths, and proportions
• Multiple revision rounds until the design matches your exact specifications
• Final digital approval before advancing to physical production

The CAD phase typically takes 5-10 business days, depending on complexity. This is where changes are easiest and least costly to implement — making thorough review at this stage essential.

Phase 2: Wax Model & Prototype

Once the digital design is approved, a physical wax model is created using precision printing technology. This wax prototype serves as the exact template for the final metal piece.

Key considerations:

• The wax model allows you to evaluate proportions and dimensions in physical form
• Stone settings can be verified for proper fit
• Any final adjustments are made before committing to precious metal
• Photography of the wax model is provided for your review and approval

Phase 3: Precious Metal Casting

The casting process transforms the wax model into your chosen precious metal — whether 18K gold (yellow, white, or rose), platinum, or sterling silver.

The process involves:

• Encasing the wax model in a heat-resistant investment material
• Heating to remove the wax, creating a precise negative mold
• Pouring molten precious metal into the cavity under controlled conditions
• Cooling and careful extraction of the raw casting
• Initial cleaning and inspection of the metal form

Casting quality depends heavily on the expertise of the foundry and the purity of materials used. This is why working with verified, experienced manufacturers is critical for premium results.

Phase 4: Stone Setting

If your piece incorporates gemstones, the setting phase requires exceptional precision and skill. Different setting styles include:

• Prong setting: Metal claws hold the stone, maximizing light exposure
• Bezel setting: A metal rim surrounds the stone, offering security and a modern aesthetic
• Pavé setting: Multiple small stones set closely together for continuous sparkle
• Channel setting: Stones set between two metal walls, creating a smooth surface

Each setting style requires different expertise and affects both the appearance and durability of the finished piece.

Phase 5: Finishing & Polishing

The finishing phase transforms a raw casting into a refined luxury piece:

• Progressive polishing to achieve the desired surface finish (mirror, matte, brushed, or combination)
• Edge refinement and comfort fitting
• Rhodium plating for white gold pieces (enhances whiteness and durability)
• Final cleaning and preparation for presentation

Phase 6: Quality Evaluation & Documentation

Before any piece leaves the workshop, a comprehensive evaluation is conducted:

• Visual inspection under controlled lighting conditions
• Verification of stone security and setting integrity
• Measurement confirmation against original specifications
• High-definition photography from multiple angles
• Documentation package prepared for client review

At ChinaProxyBuy, this evaluation is conducted independently — ensuring objective reporting before you authorize shipment. Learn more about our structured process.

Timeline Expectations

A typical bespoke jewelry project follows this timeline:

• CAD design: 5-10 business days
• Wax prototype: 3-5 business days
• Casting & setting: 7-14 business days
• Finishing & evaluation: 3-5 business days
• International shipping: 3-5 business days (express courier)

Total timeline: approximately 3-5 weeks from design approval to delivery, depending on complexity and revision requirements.

Working with a Sourcing Partner

Commissioning bespoke jewelry from international manufacturers requires careful coordination. A professional sourcing concierge manages the entire workflow — from translating your design vision to the manufacturer, through production oversight, to final quality verification and secure delivery.

This structured approach eliminates the communication gaps and quality uncertainties that often challenge direct international commissions.
