How to choose the right tennis jewellery manufacturer?

Start with evidence rather than factory adjectives. Request close-up images of links, clasp transitions, stone seats, polishing marks, and the reverse side of finished pieces. A sample should be checked for consistent dimensions, smooth edges, secure stones, clasp engagement, and alignment when the bracelet is flexed. Ask which inspection points are recorded and whether the approved sample becomes the visual and dimensional reference for bulk production. Factory size or a large style catalog does not prove control of a particular construction; the relevant evidence is repeatable output against an agreed specification.

Inspect the sample under magnification and perform controlled handling before discussing price. Check whether stones sit at a consistent height, whether settings catch fabric or skin, and whether the links articulate without binding. Open and close the clasp repeatedly, examine soldered or joined areas, and compare measured bracelet length with the drawing. For plated pieces, record the base metal, finish, color reference, and any stated coating thickness; visual color alone cannot establish wear performance. Keep an approved sample, annotated drawings, and defect limits so quality control is not based on memory.

MOQ should be evaluated by style, finish, size, and packaging configuration, not only by total purchase quantity. Separate development samples, tooling or setup charges, and repeat-order conditions in the quotation. Lead time should identify the start event, such as approved sample, confirmed specifications, deposit, or material availability, and should distinguish sampling from bulk production. Build time for artwork approval, revisions, inspection, packaging, and freight into the launch schedule. A lower unit price can become commercially unsuitable if a high MOQ ties up cash or if an unclear production clock creates stock gaps.

Specify the base metal, alloy designation, stone type, stone dimensions, setting method, surface finish, plating or vermeil construction, and intended wear environment. Sterling silver marked 925 refers to 92.5% silver, with the balance made from other alloying metals; it should not be treated as identical to brass or gold-plated brass. For vermeil, define the silver base, gold karat, color, and coating specification according to the destination market and applicable rules. Durability also depends on link geometry, clasp design, polishing, skin chemistry, abrasion, and exposure to cosmetics or water, so material selection cannot be judged from color alone.

First identify the destination markets and the exact obligations for metals, coatings, stones, packaging, and restricted substances. Ask for material declarations, supplier traceability, and test documentation that identifies the submitted sample, date, method, and applicable limit; a generic compliance logo is not equivalent evidence. REACH and RoHS have different scopes and should not be treated as interchangeable labels. Confirm whether testing covers the finished article or only an incoming raw material. Contract documents should define who owns corrective action if a batch fails, while the buyer should retain the approved specification and records for each production lot.

A usable quotation should identify the style reference, drawings, dimensions, stone count and size, metal and purity, surface treatment, plating or vermeil details, clasp, packaging, logo requirements, quantity breaks, currency, tooling or sampling charges, and shipping assumptions. It should also state the sample revision policy, production lead time, payment terms, inspection basis, and what can change the price. Ask the supplier to separate one-time development costs from the unit price and to state the validity period. Comparing quotations is meaningful only after the technical scope is normalized; otherwise a cheaper offer may simply omit testing, packaging, or finishing requirements.
