A custom engagement ring usually moves through design, specification, approval, production, finishing, and final review.

1. Define the brief

The buyer identifies stone shape, dimensions, metal, setting style, band width, profile, budget, and any wedding-band requirements.

2. Confirm feasibility

The design is checked for stone security, durability, resizing, comfort, manufacturing limits, and cost.

3. Create and approve the design

Some rings require a CAD model or detailed drawing. The buyer should review proportions, structure, and confirmed specifications before production begins.

4. Production and finishing

The ring is cast or fabricated, set, polished, inspected, and adjusted as needed.

5. Final documentation

Keep the approved specifications, measurements, receipts, and any stone documents. Custom timelines and revision rules differ by jeweler.
