Brands, retailers, wholesalers and designers build every category here in 925 sterling silver with AAA cubic zirconia or moissanite. Start from our design library at 25 pieces per style, or send your drawing for OEM and ODM from 100 pieces. 3D drawings in 1-3 days, samples in 7-15 days, bulk in 25-40.
Answer: Vet a silver OEM/ODM partner with six checks before you pay any deposit: confirm the physical workshop exists, match test reports to the exact alloy you are buying, judge finish and stone setting on a real sample, get MOQ and tooling terms in writing, sign an NDA before releasing CAD files, and treat any quote far below the live silver price as a warning. A partner that passes all six will quote within 24 hours and show the floor on video without hesitation.
Anyone can publish a catalogue. What separates a manufacturer from a middleman is whether design, mould making, casting, polishing and stone setting happen under one roof. Ask for a live video walkthrough and let them pan across the floor without cutting away. Our workshop in Haifeng, Guangdong, 70+ specialists, 5 lines and 20+ machines on a 14-step in-house process, so a technical question gets answered by pointing a camera at the station.
If a supplier can only show an office or stock photos of machinery, price the quote as a trading margin, not a factory cost.
Ask for the business licence, then for test reports by name, and check three things: the alloy listed (925 sterling, not brass), the finish tested (polished, or plated and at what thickness), and the issuing laboratory. A REACH report on gold-plated brass tells you nothing about a silver ring. SGS, REACH, RoHS and ASTM standards, and those documents are issued per product family.
Order a sample and use your own eyes and hands. Rub the surface with a white cloth: patchy colour or a grey smear means thin or uneven plating. Prongs should sit flat and every stone should sit level; tug each one gently, because a well-set stone does not rock. Measure a few pieces with a caliper, since width and thickness drifting across a batch is the first sign of a loose process.
We plate at 0.1–0.3 micron as standard and adjust it when a market needs a heavier layer, so thickness is a specification you can request.
On silver the metal portion moves with the market, so agreeing a number without a validity window is how disputes start. Our MOQ is 25 pieces for futures orders, 100 for fully personalised work and 100+ for 18K gold-plated customisation; a USD 30+ plate fee applies to custom tooling, scaled by difficulty and gram weight, and is refunded once cumulative volume across your account reaches 100 pieces. Sampling runs 7–15 days, bulk 25–40 days after deposit, and quotes hold for 24 hours because silver is priced from the day's spot rate.
Sign an NDA first, then release the technical pack in stages. Start with a reference image and a size range, move to a dimensioned drawing once the NDA is countersigned, and leave the full CAD until the sample is approved. Ask in writing whether the mould is used for any other buyer. If a supplier offers to reproduce another brand's piece item for item, treat it as legal risk you are inheriting, not a service.
A workable rhythm is: sample, measure, approve in writing, pay 30% deposit, produce in 25–40 days, inspect, then ship. Ask what happens if a piece fails inspection, before the carton is sealed. Non-human-caused quality issues reported within 7 days are compensated at 100%, and per-batch records let an issue be traced to a workstation; anything outside that window is discussed case by case.
