MANUFACTURING
How Jewelry Manufacturing Works from CAD to Finished Piece
Jewelry manufacturing turns an approved design into prepared metal components, set stones and a finished piece through sampling, production and inspection.
PROJECT ROUTES
OEM vs ODM Jewelry Manufacturing
OEM starts with a client-supplied design for manufacturing; ODM starts with an idea that needs product design and CAD development before manufacture.
PRIVATE LABEL
How to Start a Private Label Jewelry Collection
A private label collection can begin without CAD: select a product direction, define the customer and price position, then develop samples and brand presentation.
CAD & FILES
What Files Should You Send a Jewelry Manufacturer?
Send the current design file with units, dimensions, material and stone requirements, plus a drawing or image that identifies the critical features.
SAMPLING
How Jewelry Samples Are Approved
Approve a jewelry sample against a written specification and revision record, recording any corrections before the agreed production stage begins.
SMALL BATCH
How Small-Batch Jewelry Manufacturing Works
Small-batch jewelry manufacturing starts with an approved product specification and a feasible quantity, balancing development, tooling, material and inspection requirements.
