Round Cut Lab Grown Diamond Made to Order: Carton Cube, Duty and the Freight Line Tha - HOLYCOME
Round Cut Lab Grown Diamond: tolerances, cost structure and the reject rule for US wholesale buyers.
Carton Cube, Duty and the Freight Line That Surprises Buyers in the Made to Order Program
A US buyer of round Cut Lab Grown Diamond sent us a competitor's round Cut Lab Grown Diamond in March with one question: why does this fail at certificate mismatch after a season. We measured it, rebuilt the spec around report plot match and table percentage within the stated band, and shipped 50 round Cut Lab Grown Diamond that cleared inspection with zero rejects, certified IGI report and packed single-piece foam box at 50 pieces.
At 50 pieces the buyer was not buying a defect, they were buying a document. The Made to Order order carried a photo and a price, and certificate mismatch had nowhere to live, and the Made to Order quote for it sits at USD 150-1225.
Our rebuild kept the buyer's retail price and changed four numbers on the bench. The next run cleared inspection because the specification traveled with the tray, not with a phone call, certified IGI report and packed single-piece foam box at 50 pieces, shipped as single-piece foam box and certified IGI report.
The Made-to-Order Path for round Cut Lab Grown Diamond
Made-to-order is a different production line, not a slower version of stock. It starts with a signed drawing, then a wax or resin model, then a casting, then setting, then finish, and each stage can fail on its own, which is USD 150-1225 on the Made to Order schedule.
Twenty days is realistic for a new round Cut Lab Grown Diamond when the model exists and only the stone changes. A new model adds a day for the CAD, a day for the print, and a day for the buyer to approve the render before metal is committed, the figure being USD 150-1225 for a 50-piece run.
The risk sits in approval, not in the bench. A buyer who approves a render on a phone screen and rejects the casting has bought a prototype, not a product. We send the render at 1:1 scale with a millimetre grid for that reason, with IGI report and single-piece foam box stated on the same sheet.
Three Failures That Reach the Made to Order Bench
growth-method disclosure
CVD and HPHT stones behave differently under high heat during setting. Disclosing the method protects both sides in a repair claim, which is USD 150-1225 on the Made to Order schedule.
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, and the Made to Order quote for it sits at USD 150-1225.
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, and the Made to Order quote for it sits at USD 150-1225.
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, on a 50-piece Made to Order order at USD 150-1225.
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, which the Made to Order file records at USD 150-1225 in single-piece foam box.
In a 50-piece run this typically shows on 14 of pieces. Catching it means measuring report plot match at the tray level, not inspecting the finished carton, on a 50-piece Made to Order order at USD 150-1225.
Four Spec Lines a Made to Order Buyer Checks
Most quotes describe the round Cut Lab Grown Diamond and skip the part that determines the buyer's margin. Those four lines are listed below with the trade default beside our standard, the figure being USD 150-1225 for a 50-piece run.
| Spec point | Common trade output | HOLYCOME standard | Cost if missed |
|---|---|---|---|
| Clasp spring life | Sampled by hand | Cycled 500 times on a jig per lot | Detach claim and brand damage |
| Prong tension and seat depth | Checked by feel at the bench | Pull-tested per piece, seat depth written on the sheet | Stone loss and total replacement |
| 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 |
Write these four into the purchase order and the argument after delivery becomes arithmetic rather than recollection, shipped as single-piece foam box and certified IGI report, quoted at USD 150-1225 per piece in single-piece foam box.
Terms Behind a Made to Order Order
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 50-piece Made to Order 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, priced at USD 150-1225 for the 50-piece Made to Order run.
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 150-1225 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 single-piece foam box format at 50 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.
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, which the Made to Order file records at USD 150-1225 in single-piece foam box.
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, which is how the Made to Order account reads it at USD 150-1225.
Cost Split on a Made to Order Piece at USD 150-1225
At USD 150-1225 per piece for round Cut Lab Grown Diamond, the stone is roughly a quarter and labor is where two quotes for the same drawing diverge.
| Cost line | Share | What moves it |
|---|---|---|
| Base metal or alloy for round Cut Lab Grown Diamond | 32% | Alloy choice and casting yield |
| Stone or melee for round Cut Lab Grown Diamond | 23% | Sieve range and lot batching |
| Setting and finishing labor for round Cut Lab Grown Diamond | 21% | Jig design and bench minutes |
| Plating, polish and QC for round Cut Lab Grown Diamond | 14% | Per-tray versus per-piece checks |
| Packaging for round Cut Lab Grown Diamond | 10% | single-piece foam box |
The saving in the cheapest round Cut Lab Grown Diamond quote hides in the plating line and the stone grade. Both appear in season two, not on arrival, which is USD 150-1225 on the Made to Order schedule.
What a Report Proves and What It Does Not
Nobody quotes it for round Cut Lab Grown Diamond until something goes wrong, which is exactly why it belongs in the first email, which the Made to Order file records at USD 150-1225 in single-piece foam box.
Three numbers decide it for round Cut Lab Grown Diamond: the tolerance band, the inspection density and the responsibility clause. Write all three down and the rest of the negotiation is arithmetic. Leave any of them out and it becomes a discussion about intent, priced at USD 150-1225 for the 50-piece Made to Order run.
We send a one-page sheet with every round Cut Lab Grown Diamond quote that states those three, plus the retained-tray rule. Buyers who compare on it usually find that the gap between suppliers is smaller than the gap between the specs they were comparing, priced at USD 150-1225 for the 50-piece Made to Order run.
The Sample Approval That Survives Production
It is not a marketing point on round Cut Lab Grown Diamond. It is the number that decides whether the second order happens, which the Made to Order file records at USD 150-1225 in single-piece foam box.
There is a version of this that looks cheaper on paper and costs more in practice: quoting the best case on round Cut Lab Grown Diamond and letting the buyer discover the spread. It works once. The second order goes to whichever supplier quoted honestly, and the Made to Order quote for it sits at USD 150-1225.
We would rather lose a first order of round Cut Lab Grown Diamond on price than explain a defect after it lands. That position is unusual in this category and it is the reason our reorder share is high, and the Made to Order quote for it sits at USD 150-1225.
The First Made to Order Order
The point of a small first run is not the margin. It is finding out whether the supplier's paperwork survives contact with the actual goods, which is how the Made to Order account reads it at USD 150-1225.
The first order is the cheapest inspection a buyer will ever run, because the volume is small enough to check every tray by hand, which the Made to Order file records at USD 150-1225 in single-piece foam box.
Getting single-piece foam box to the US market
Export runs through Guangzhou or Shenzhen. For Made to Order orders the IGI report file travels with the shipping documents, not separately, which is USD 150-1225 on the Made to Order schedule.
The clearance term matters more than the rate at 50 pieces. A duty surprise can cost more than the whole freight line, which is how the Made to Order account reads it at USD 150-1225.
The arrival check is three steps: count cartons against the packing list, weigh a sample tray, and measure ten pieces against report plot match and table percentage within the stated band, and 50 pieces leaves Wuzhou in single-piece foam box at USD 150-1225.
