Lab Grown Diamond Sets Valentine Program: AQL, Tray Checks and What a QC Report Shoul - HOLYCOME
Lab Grown Diamond Sets: tolerances, cost structure and the reject rule for US wholesale buyers.
AQL, Tray Checks and What a QC Report Should Say
The brief was simple: 300 lab Grown Diamond Sets, 14K/18K gold or platinum with IGI-certified lab-grown diamond, delivered before February. The run that arrived carried 17 pieces with certificate mismatch, and the buyer spent USD 50-265 on sorting before the goods reached a shelf, which the Valentine Program file records at USD 134-1097 in heart gift box.
Nobody on that bench was careless. They were working to a spec that existed only in a photograph, and certificate mismatch is what a photograph fails to define, the figure being USD 134-1097 for a 300-piece run.
The fix cost about 26 seconds per lab Grown Diamond Set and removed the credit note entirely. That is the whole economics of a spec sheet, and it is why we write one on every quote, shipped as heart gift box and certified IGI report, shipped as heart gift box and certified IGI report.
What US buyers Check Before They Sign
Four lines decide whether lab Grown Diamond Sets at USD 134-1097 sells through or comes back, and none of them appears on a typical trading-company quote.
| Spec point | Common trade output | HOLYCOME standard | Cost if missed |
|---|---|---|---|
| Hallmark depth and placement | Stamped where it fits | Fixed position, depth measured so it never breaks the shank | Customs query and remaking |
| Solder flow at the joint | Not inspected | Joint inspected under 10x before setting | Crack at the seam in transit |
| Plating thickness | Nominal only | 0.20 micron rhodium logged per lot, 3 microns on vermeil | Wear-through inside one season |
| Surface porosity after polish | Seen after plating | Cast porosity checked before plating, rejects pulled at that stage | Plating blister six weeks later |
Put these four into the purchase order and the Valentine Program argument after delivery becomes arithmetic, quoted at USD 134-1097 per piece in heart gift box.
Where USD 134-1097 Per Piece Actually Goes
Cost per piece at USD 134-1097 leaves little room for assumption. The table shows which line compresses and which one only moves quality.
| Cost line | Share | What moves it |
|---|---|---|
| Base metal or alloy for lab Grown Diamond Sets | 30% | Alloy choice and casting yield |
| Stone or melee for lab Grown Diamond Sets | 20% | Sieve range and lot batching |
| Setting and finishing labor for lab Grown Diamond Sets | 19% | Jig design and bench minutes |
| Plating, polish and QC for lab Grown Diamond Sets | 12% | Per-tray versus per-piece checks |
| Packaging for lab Grown Diamond Sets | 19% | heart gift box |

Order Terms, Sample Timing and Packing
The commercial frame is short enough to state in full. Minimum order is 50 pieces per design, and mixed designs travel in one shipment, so a 300-piece Valentine Program order can carry three or four models without a separate setup charge. Sample pieces leave in 3-5 days when the components are in stock, and a new model adds about twenty days before the first article exists, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.
Payment is 30 percent with the order and 70 percent against the bill of lading, with the balance window stated on the invoice rather than agreed by message. Prices quoted at USD 134-1097 are FOB Guangzhou or Shenzhen; DDP is quoted separately because the duty line moves with the tariff schedule and not with our cost.
Packing follows the heart gift box format at 300 pieces to the carton, and the packing list carries SKU, size and stone size so receiving can count without opening every box. Private-label cartons add three days for the print run and must be approved before the first bulk order, not after it, with IGI report and heart gift box stated on the same sheet.
Certification is IGI report for the lots that carry it, with a batch report and per-piece measurement of report plot match for the lots below the threshold. The document set travels with the shipping papers, which is what a customs broker asks for at the port rather than after clearance, certified IGI report and packed heart gift box at 300 pieces.
A rejected tray is settled inside the same order cycle against the retained reference piece. If the difference sits on our retained sample we replace or credit; if it appeared in transit we split the assay cost and file with the carrier, and that rule is written on the order before the deposit clears, quoted at USD 134-1097 per piece in heart gift box.
The Three Failures We See Most in Incoming Samples
certificate mismatch
A stone whose report says VS1 but whose plot shows a cloud near the table reads as a grade dispute at the counter. Match the plot, not only the grade line, certified IGI report and packed heart gift box at 300 pieces.
In a 300-piece run this typically shows on 11 of pieces. Catching it means measuring report plot match at the tray level, not inspecting the finished carton, and at USD 134-1097 for 300 pieces that is the number the buyer signs.
growth-method disclosure
CVD and HPHT stones behave differently under high heat during setting. Disclosing the method protects both sides in a repair claim, with IGI report and heart gift box stated on the same sheet.
The commercial effect is stone replacement at a four-figure cost, plus a disclosure review. Buyers who have seen it once put it in the purchase order; buyers who have not usually discover it on the first return, which is how the Valentine Program account reads it at USD 134-1097.
table percentage variance
A 62% table in a bright cut reads dark in a store window. Buying by table percentage, not only by carat, keeps the display consistent, which is how the Valentine Program account reads it at USD 134-1097.
Our countermeasure is a gauge and a written limit. It adds about 26 seconds per piece and removes the defect from the run rather than from the carton, priced at USD 134-1097 for the 300-piece Valentine Program run.
AQL, Tray Checks and What a QC Report Should Say
Most lab Grown Diamond Sets disputes we arbitrate trace back to this line, not to the defect itself, on a 300-piece Valentine Program order at USD 134-1097.
At 300 pieces the arithmetic on lab Grown Diamond Sets changes: the fixed costs spread, the variable costs do not. That is why the second order prices better than the first even when the gold fix has moved up, priced at USD 134-1097 for the 300-piece Valentine Program run.
We quote both a first-run price and a reorder price for lab Grown Diamond Sets on the same sheet so the buyer can see where the curve flattens. Most flatten by the third run, which is USD 134-1097 on the Valentine Program schedule.
Carton Cube, Duty and the Freight Line That Surprises Buyers
On lab Grown Diamond Sets, the cheapest answer is rarely the cheapest outcome once the second season is counted, which the Valentine Program file records at USD 134-1097 in heart gift box.
One practical note on timing for lab Grown Diamond Sets: the calendar starts when the spec is signed, not when the deposit clears. A buyer who signs in week one and pays in week three gets the goods in week five, and at USD 134-1097 for 300 pieces that is the number the buyer signs.
We date the lab Grown Diamond Sets proforma from signature for that reason, and we state the deposit deadline in the same email that carries the spec sheet, on a 300-piece Valentine Program order at USD 134-1097.
Valentine Window for lab Grown Diamond Sets
The Valentine window is short and unforgiving: stock has to be in the warehouse by the last week of January or the season is gone. That puts the production order in the second week of December, ahead of the Lunar New Year slowdown, shipped as heart gift box and certified IGI report.
Paired designs move better than single pieces here. A matching pair of lab Grown Diamond Sets, boxed together with two cards, converts at the same retail price as two singles and costs about nine percent more to make, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.
Photography has to be red-and-white neutral. A lab Grown Diamond Set shot on a red silk background reads as a gift in a listing thumbnail, and that is the only image most buyers will ever see, and the Valentine Program quote for it sits at USD 134-1097.
How a Repeat Order Gets Built
The sequence below is fixed for a Valentine Program run. The dates move with the stone lot, not with the shipping season, and the Valentine Program quote for it sits at USD 134-1097.
- Lock the spec: metal, stone size range, plating thickness, sizing band and finish, all written on one sheet.
- Pull a stock-component sample in 3-5 days and measure it against that sheet, not against the photo.
- Approve the sample in writing, including the reject rule and the retained reference tray.
- Run bulk in 15-20 days for orders under 500 pieces, with the gauge check independent of the shift.
- Ship from Guangzhou or Shenzhen with the QC sheet in the carton and the batch report by email.
Reorders inside this sequence run 12-15 days, because the model and the gauge set stay here after the Valentine Program shipment, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.
What This Means for a First Order
A first Valentine Program order of 50 pieces per design at USD 134-1097 is a test of the line, not a commitment to the range.
Ask for the retained tray and the batch report with the first shipment. Both are free and both decide the second order, certified IGI report and packed heart gift box at 300 pieces, priced at USD 134-1097 for the 300-piece Valentine Program run.
Freight, Duty and the Arrival Check
Export runs through Guangzhou or Shenzhen. Air freight lands in 5-8 days on the US west coast and 7-10 on the east, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.
For a first order, DDP matters more than the freight rate. The surprise is the duty line, not the per-kilo charge, which is how the Valentine Program account reads it at USD 134-1097.
Check the count, the weight and report plot match and table percentage within the stated band before the carton goes to the shelf. Twenty minutes at receiving saves a season of returns, which the Valentine Program file records at USD 134-1097 in heart gift box.
Frequently Asked Questions

How do you handle a rejected tray?
