What luxury brands expect from an OEM jewelry manufacturer

Ask for records that connect the approved design to the production controls used for the order. Depending on the product, these may include controlled drawings or specifications, material declarations or supplier documents, inspection criteria, sample approvals, and records of final inspection. Clarify which characteristics are checked, how results are recorded, and what happens when an item does not meet an agreed criterion. A generic certificate is not a substitute for product-specific evidence, and the existence or scope of any quality system should be verified directly.

Treat sample approval as a documented design and workmanship decision, not proof that every production unit will be identical. Identify the approved sample by version, date, and relevant design files; record finish, dimensions, stone placement, closures, and other critical features. Ask how the production process will reproduce those features and which checks will detect variation. If materials or construction change after approval, require a revised review rather than relying on the earlier sample. A pre-production sample can reduce ambiguity, but it cannot replace agreed inspection criteria and change control.

Prioritize characteristics that affect fit, function, appearance, or assembly: dimensions that determine how components join, ring or chain sizing, stone position and security, symmetry, surface finish, and closure operation. Do not assume that a drawing alone defines acceptable variation; drawings should specify units, measurement locations, and tolerances for critical features. For visual qualities such as polish or color, define reference conditions and review methods because subjective terms like “perfect match” are difficult to enforce. Agree on measurement tools and acceptance rules before production, especially where several components must fit together.

A useful quotation separates the pricing basis from assumptions that can change the final cost. Ask how metal price is referenced and when it is fixed, whether the estimate uses gross or net metal weight, how expected process loss or recoverable scrap is handled, and how stones, labor, finishing, packaging, and freight are treated. Confirm the purity and metal specification, currency, quote validity, payment terms, and the approval process for weight or design changes. Precious-metal prices fluctuate, so a quote should state its pricing basis and adjustment method rather than imply that an early estimate is a fixed final cost.

First define what traceability means for the order: identification of the supplied metal, links between material batches and production records, or documentation of upstream origin are different levels of evidence. Request documents that match the claim being made, such as supplier declarations, transaction records, batch identifiers, and order-level material records where available. Check that names, dates, quantities, and material descriptions are consistent across records. Hallmarking and disclosure rules vary by destination market and product, so verify applicable legal requirements with the relevant authority or qualified compliance adviser; a hallmark by itself does not establish a complete upstream chain of custody.

Before sharing detailed CAD files or drawings, define confidentiality and permitted use in a written agreement reviewed for the relevant jurisdictions. Identify which files, samples, and derivative designs are covered; who may access them; whether subcontracting is permitted; and how files must be stored, returned, or deleted when work ends. Use version control and share only the information needed for each development stage. Clarify ownership of pre-existing tools, newly created designs, and production tooling separately, since ownership of a design file does not automatically settle every intellectual-property or tooling right. Have counsel review the agreement for the project’s markets.
