Documents Included Free with Every Order
Every bulk shipment includes a commercial invoice and packing list showing HS codes (typically 7117.19 for imitation jewelry or 7113.11 and 7113.19 for precious metal jewelry), SKU breakdown, piece count, gross and net weight, and carton dimensions. A factory Declaration of Conformity states that products comply with EU REACH regulation EC 1907/2006 and EU RoHS 2 directive 2011/65/EU for restricted substances including lead, cadmium, phthalates, and nickel. In-house XRF metal composition reports are available per batch showing silver or gold purity.
Optional Third-Party Reports
Nickel release testing per EN 1811 is required in the EU for jewelry pierced into skin or in prolonged skin contact. HOLYCOME arranges SGS or Intertek testing at approximately 150 US dollars per material type with a five to seven working day turnaround. REACH SVHC screening and California Prop65 heavy metal testing are available in similar price ranges. For US shipments to California, Prop65-compliant warning labels can be applied to packaging on request.
Stone Grading Reports
Per-stone moissanite grading reports are available from GRA (Global Gemological Research Association) for D-color VVS1 moissanite above 0.5 carat at 2 to 5 US dollars per stone depending on size. Buyers should note that GRA is a commercial moissanite industry laboratory and is not the Gemological Institute of America. The GIA grades natural diamonds and lab-grown diamonds but does not grade moissanite; any document claiming to be a GIA moissanite certificate is not an authentic GIA report. HOLYCOME accurately labels all moissanite as moissanite in documentation and metal stamping, never as diamond, in accordance with FTC Jewelry Guides.
For independent references, see the Gemological Institute of America for gemological standards, the FTC Jewelry Guides for marketing disclosure rules, and EUR-Lex for EU REACH regulation text.
Practical Sourcing Tips for First-Time Buyers
For buyers placing their first order with a new manufacturer, several practical steps substantially reduce risk. Start with a small sample order of one to three pieces before committing to bulk. Evaluate packaging, stamping accuracy, stone alignment, polish quality, and rhodium finish on the physical sample rather than relying on photos alone. Confirm that communication with the account manager is clear and responsive. Request production photos at the casting and setting stages on the first order to verify progress and address problems early.
When inspecting samples, check that ring sizes match ordered specifications within 0.10 millimeters, that stone spacing is consistent in pave layouts, that clasps open and close with positive resistance, that earring posts are straight and firmly soldered, that chain links have no gaps, that plating is even on hidden areas such as the inside of bands and the backs of pendants, and that metal stamps are legible and correctly placed. Catching these issues on the sample prevents defective pieces in bulk production.
Send written approvals by email listing any corrections needed before bulk starts. Verbal approvals over chat can be misremembered; email creates a clear record both sides can reference during final inspection. For Q4 holiday selling, place orders by the end of August at the latest to leave time for production, shipping, customs, and any reorders needed before Black Friday and Christmas.
Time Zones, Communication, and Factory Visits
HOLYCOME account managers operate on Chinese business hours, 9am to 6pm GMT+8 Monday through Saturday. For US East Coast buyers this is evening Eastern Time; for EU buyers it is midday to afternoon Central European Time. Response times are within 24 hours for inquiries, and same-day for urgent production matters during business hours. All production documentation, quotations, invoices, and inspection reports are issued in English. Video calls and virtual factory tours can be scheduled in advance.
HOLYCOME regularly exhibits at JCK Las Vegas, the Hong Kong Jewellery and Gem Fair in September, and Vicenzaoro in January and September. Meeting in person at a trade show is an efficient way to review samples, discuss new designs, and align on production plans. Buyers are also welcome to visit the Wuzhou factory directly; HOLYCOME can arrange airport pickup from Guangzhou Baiyun International Airport or Wuzhou Xijiang Airport on request.
Building Long-Term Manufacturing Partnerships
The most successful B2B relationships in jewelry manufacturing are long-term partnerships, not one-off transactions. Brands placing consistent monthly or quarterly orders receive priority production scheduling, preferential pricing as volumes scale, early access to new designs, and increasingly flexible payment terms. HOLYCOME works with many clients who started with 50-piece trial orders and grew to multi-thousand-piece monthly programs over one to two years. Growth on both sides is the objective.
Open communication about sales performance helps manufacturers plan better. When a design sells out faster than expected, sharing that information early lets the factory reserve capacity for the reorder before the production queue fills for peak season. When a design underperforms, that feedback helps the factory suggest alternatives better matched to the brand's customer base.
