Marquise Cut Lab Grown Diamond: tolerances, cost structure and the reject rule for US wholesale buyers.

Marquise Cut Lab Grown Diamond Made to Order: Carton Cube, Duty and the Freight Line - HOLYCOME

Carton Cube, Duty and the Freight Line That Surprises Buyers

Last January, a US buyer of marquise Cut Lab Grown Diamond placed 50 marquise Cut Lab Grown Diamond against a sample signed in May. The first container landed with 9 pieces that failed on certificate mismatch alone, and USD 55-290 landed on the buyer's P&L before a single unit sold, which is how the Made to Order account reads it at USD 150-1225.

The incoming report named certificate mismatch and the purchase order did not. On a Made to Order run that gap between documents is the whole reason a tray fails inspection, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

We did not touch the retail price. We changed what travels with the single-piece foam box carton, and the Made to Order account stopped re-inspecting every tray, priced at USD 150-1225 for the 50-piece Made to Order run.

The Made-to-Order Path for marquise 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

Twenty days is realistic for a new marquise 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, on a 50-piece Made to Order order at USD 150-1225.

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, on a 50-piece Made to Order order at USD 150-1225.

The Three Failures We See Most in Incoming Samples

growth-method disclosure

CVD and HPHT stones behave differently under high heat during setting. Disclosing the method protects both sides in a repair claim, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

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, which is USD 150-1225 on the Made to Order schedule.

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, priced at USD 150-1225 for the 50-piece Made to Order run.

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, priced at USD 150-1225 for the 50-piece Made to Order run.

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 is how the Made to Order account reads it 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, which is USD 150-1225 on the Made to Order schedule.

What US buyers Check Before They Sign

A quote for marquise Cut Lab Grown Diamond usually states carat weight or metal type, and stops there. The four points below are what actually decide whether a run sells through or comes back, certified IGI report and packed single-piece foam box at 50 pieces, and the Made to Order quote for it sits at USD 150-1225.

Spec pointCommon trade outputHOLYCOME standardCost if missed
Clasp spring lifeSampled by handCycled 500 times on a jig per lotDetach claim and brand damage
Prong tension and seat depthChecked by feel at the benchPull-tested per piece, seat depth written on the sheetStone loss and total replacement
Hallmark depth and placementStamped where it fitsFixed position, depth measured so it never breaks the shankCustoms query and remaking
Solder flow at the jointNot inspectedJoint inspected under 10x before settingCrack at the seam in transit

Each line above is a gauge check, not a marketing claim. A factory that cannot state them in numbers is quoting an opinion about marquise Cut Lab Grown Diamond, the figure being USD 150-1225 for a 50-piece run.

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 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, with IGI report and single-piece foam box stated on the same sheet.

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, shipped as single-piece foam box and certified IGI report.

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 is how the Made to Order account reads it at USD 150-1225.

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, and 50 pieces leaves Wuzhou in single-piece foam box at USD 150-1225.

Where USD 150-1225 Per Piece Actually Goes

At USD 150-1225 per piece there is no room for hidden cost. The table shows where the money sits and which line a supplier can actually compress.

Cost lineShareWhat moves it
Base metal or alloy for marquise Cut Lab Grown Diamond30%Alloy choice and casting yield
Stone or melee for marquise Cut Lab Grown Diamond20%Sieve range and lot batching
Setting and finishing labor for marquise Cut Lab Grown Diamond19%Jig design and bench minutes
Plating, polish and QC for marquise Cut Lab Grown Diamond12%Per-tray versus per-piece checks
Packaging for marquise Cut Lab Grown Diamond19%single-piece foam box

A supplier with no bench minutes per piece has never costed marquise Cut Lab Grown Diamond. Ask for minutes and the reject rule before you ask for a discount, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

What a Report Proves and What It Does Not

Ask three suppliers of marquise Cut Lab Grown Diamond this question and you will get three answers. Only one of them survives an inspection, priced at USD 150-1225 for the 50-piece Made to Order run.

Three numbers decide it for marquise 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, which is USD 150-1225 on the Made to Order schedule.

We send a one-page sheet with every marquise 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, which is how the Made to Order account reads it at USD 150-1225.

The Sample Approval That Survives Production

On marquise Cut Lab Grown Diamond, the difference between a 40-day order and a 90-day order is usually two signatures, not a factory delay, which is USD 150-1225 on the Made to Order schedule.

There is a version of this that looks cheaper on paper and costs more in practice: quoting the best case on marquise Cut Lab Grown Diamond and letting the buyer discover the spread. It works once. The second order goes to whichever supplier quoted honestly, on a 50-piece Made to Order order at USD 150-1225.

We would rather lose a first order of marquise 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, with IGI report and single-piece foam box stated on the same sheet.

What This Means for a First Order

A first order of 50 pieces per design is a measurement, not a purchase. It shows how report plot match and table percentage within the stated band behaves on this line and whether the QC sheet matches the carton, and 50 pieces leaves Wuzhou in single-piece foam box at USD 150-1225.

Six weeks of testing is cheaper than a season of returns on marquise Cut Lab Grown Diamond. That is the entire argument for a small first order, which is how the Made to Order account reads it at USD 150-1225.

Freight, Duty and the Arrival Check

At 50 pieces the carton count drives freight more than the weight. single-piece foam box packs tighter than a display tray and saves a pallet position, which is USD 150-1225 on the Made to Order schedule.

FOB Guangzhou or Shenzhen is the default on marquise Cut Lab Grown Diamond. Buyers new to North American retail take DDP once and switch after they see the breakdown, priced at USD 150-1225 for the 50-piece Made to Order run.

If certificate mismatch shows in the arrival check, the retained tray decides ownership. Keep the IGI report sheet beside the packing list, quoted at USD 150-1225 per piece in single-piece foam box.

How a Repeat Order Gets Built

Nothing in this sequence is clever. Each step exists because skipping it produced a specific failure on a previous order of marquise Cut Lab Grown Diamond, which is USD 150-1225 on the Made to Order schedule.

  1. Sign the drawing at 1:1 scale with a millimetre grid, not a phone render.
  2. Cut the model in wax or resin and photograph it on the gauge before metal is committed.
  3. Cast the first article, set the stones and finish it exactly as bulk will be finished.
  4. Send the first article for approval with the weight and the stone measurements stated.
  5. Run the balance of the order in 25-30 days, holding the approved article as the reference.
  6. Ship with the approved article photographed beside a production piece from the same tray.

Reorders run 12-15 days because the model, the gauge set and the signed spec stay in our system between the Made to Order runs, which is USD 150-1225 on the Made to Order schedule.

Frequently Asked Questions

Can you ship DDP?

DDP is available for US accounts and removes the duty invoice that arrives after the carton clears. FOB Guangzhou or Shenzhen is the default, and most buyers take DDP once and then switch after they see the breakdown, quoted at USD 150-1225 per piece in single-piece foam box.

How long does a reorder of the same marquise Cut Lab Grown Diamond take?

With the model, the gauge set and the signed spec already in our system, a repeat is 12-15 days; a first run is 3-5 days for a stock-component sample and about 20 days when a new model is needed, and the Made to Order quote for it sits at USD 150-1225.

What finish do you use, and how thick is it?

Rhodium at 0.20 micron minimum on white marquise Cut Lab Grown Diamond, with a palladium strike layer so wear-through reads white rather than yellow. Vermeil runs at 3 microns over sterling and is logged per lot, shipped as single-piece foam box and certified IGI report.

How is marquise Cut Lab Grown Diamond packed for single-piece foam box?

Every unit goes into a foam-backed pouch, then the single-piece foam box, then the outer carton at 50 pieces. The packing list carries the SKU, the size and the stone size so receiving can check without opening every box, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

Can you ship DDP?

DDP is available for US accounts and removes the duty invoice that arrives after the carton clears. FOB Guangzhou or Shenzhen is the default, and most buyers take DDP once and then switch after they see the breakdown, quoted at USD 150-1225 per piece in single-piece foam box.
