What quality tests are done before shipping?

Before any gold plated order leaves Hengdian (HD) Jewelry it passes a fixed set of checks at two sites: in-line inspection at our Shanwei, Haifeng factory and a second quality control step at our Guangzhou warehouse. The tests target the defects buyers raise: uneven plating, loose stones, wrong sizes and finish that drifts from the approved sample.
Which tests run before shipping?
The routine covers six areas, each with a pass or fail criterion. A piece that fails is held back before packing.
Visual inspection under magnification
Surface, plating uniformity, solder joints, edges and symmetry are checked by eye and under a loupe. Dents, scratches and colour patches are reject reasons.
Dimensional and weight verification
Ring sizes, chain lengths and pendant dimensions are measured with calipers and gauges, and weight is compared with the approved specification.
Plating thickness measurement
Plating is measured against our own house standard of 0.1-0.3 micron of 18K gold over brass, which we control in-house, not an industry-wide figure. Other thicknesses are available on request.
Adhesion and wear checks
Handling and rub checks confirm the plating has bonded. Pieces showing lifting, blistering or colour shift are rejected rather than packed.
Stone security and finish match
Every CZ setting is checked for tightness; stones should not move or rattle. Colour, tone and polish are compared with the approved golden sample.
Compliance and material evidence
Lead-free material and nickel release within REACH limits are supported by SGS, REACH and CE documents. We do not advertise nickel-free; we report what the documents show.
What happens when a piece fails?
Failed units are separated and reworked or replaced before the carton is closed. With 40,000+ pieces in stock and 500+ new designs added monthly, a rejected unit is normally swapped from the same run instead of delaying shipment. Custom orders use the approved sample as the reference. The full range is on our product list.
Final check before packing
The second inspection happens at our Guangzhou warehouse, after goods leave the factory. Quantities, style mix, plating tone and stone condition are re-checked against the order, then each piece is bagged. Stock orders ship in OPP bags only; custom packaging starts at 10,000 pieces. Our 1-to-1 service covers this step.
Can a buyer request specific tests?
Yes. Tell us which standard your market or retail client requires and we will confirm, before production, which reports we can supply. OEM and ODM projects also agree a pre-production sample and sign an NDA before drawings are shared. Start with our inquiry page or contact us.
Quick answers
Do you test every piece?
Visual and dimensional checks are piece by piece; material tests are backed by batch documentation and reports.
What is the minimum order?
Stock starts at 6-12 pieces per style (36 for codes beginning with HAI); 18K gold plated custom orders start at 120 pieces per design.
Can I get samples first?
Yes, 5-7 free samples. Freight is prepaid by the buyer and we dispatch once it is received.
Are stock styles mixed?
Stock is ordered per style; we do not mix different designs to fill a minimum.
Send your specification and target market, and we will confirm which tests and documents apply to your order.
