How to Request a Jewelry Prototype

A jewelry prototype should answer a defined set of questions. It may test proportions, assembly, wear, finish or the complete production route. Calling every early sample “final” makes feedback unclear and can release the wrong version.

Short answer: State what the prototype must prove, which CAD revision it represents and whether its materials and finish match production. Return one measured change list and require a new revision for every accepted correction.

Revision	Exact CAD or drawing used
Materials	Production-equivalent or deliberate substitute
Review	Dimensions, wear, stones, findings and finish
Decision	Approve, revise or reject with one change list

Define the prototype purpose

An appearance model may not prove clasp tension or plating. A construction sample may use a temporary finish. Write the questions first so reviewers do not reject a sample for something it was never intended to demonstrate.

Attach the correct design record

Reference the CAD revision, dimensions, stone schedule, metal and findings. If a substitute material or stone is used, mark it visibly in the review sheet and state what remains to be verified later.

Plan the review before arrival

Prepare checkpoints for identity, dimensions, comfort, balance, movement, settings, edges, finish, logo and packaging fit. Assign one person to consolidate comments and distinguish defects from requested design changes.

Issue measurable corrections

Replace comments such as “make it better” with a dimension, location, reference view or acceptance condition. Number each item and require the next CAD or prototype to close it explicitly.

Name the production reference

When the prototype is accepted, photograph it, record any hand corrections and connect it to the final CAD revision. The purchase order should state whether that physical piece is the master appearance and function reference.

Connect the decision to the full project

Keep this record with the jewelry design brief, the CAD and sample approval record and the production quality checklist. Send the controlled specification through the project contact page when a manufacturing review is needed.

Frequently Asked Questions

What is the difference between a jewelry prototype and sample?

The terms overlap. Define whether the piece tests appearance, construction, wear, finish or the complete production specification.

Can a jewelry prototype use substitute materials?

Yes when the purpose allows it, but every substitute and the unverified characteristic should be recorded.

How many prototype revisions are needed?

Use as many as required to close the agreed criteria. The quotation should state included revisions and how further changes are handled.

What should happen to an approved prototype?

Keep it with photographs, the final CAD revision, specification and closed change list as the production and reorder reference.
