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

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

Why the Made to Order Quote Looks Cheap Until It Lands

In April, a US buyer of radiant Cut Lab Grown Diamond ordered 50 radiant Cut Lab Grown Diamond and asked for the same 0.50 ct to 3.00 ct as a competitor's sample. What arrived matched the photo and missed the drawing, and 13 pieces had to be reworked at the buyer's expense, quoted at USD 150-1225 per piece in single-piece foam box.

Nothing in that rejection was exotic. At USD 150-1225 per piece and 50 pieces on the order, a certificate mismatch rate of two percent is a costing error rather than a quality mystery.

Cost of the fix was about 26 seconds per piece. On 50 pieces that is a few hours at the bench and the whole claim file disappears, which is USD 150-1225 on the Made to Order schedule.

The Made-to-Order Path for radiant 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, shipped as single-piece foam box and certified IGI report.

Twenty days is realistic for a new radiant 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, which the Made to Order file records at USD 150-1225 in single-piece foam box.

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

What Fails First on radiant Cut Lab Grown Diamond

growth-method disclosure

CVD and HPHT stones behave differently under high heat during setting. Disclosing the method protects both sides in a repair claim, shipped as single-piece foam box and certified IGI report.

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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

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

In a 50-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, which is USD 150-1225 on the Made to Order schedule.

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

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

The Measurements Behind a USD 150-1225 Quote

Four numbers separate a 50-piece run that clears inspection from one that generates a credit note. None of them appears on the sample photo, certified IGI report and packed single-piece foam box at 50 pieces.

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

None of these are premium features. They cost seconds per piece and they remove the reason a buyer has to inspect twice, certified IGI report and packed single-piece foam box at 50 pieces, which the Made to Order file records at USD 150-1225 in single-piece foam box.

MOQ, Samples and the Balance

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

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, the figure being USD 150-1225 for a 50-piece run.

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, and 50 pieces leaves Wuzhou in single-piece foam box 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 the Made to Order quote for it sits at USD 150-1225.

What a USD 150-1225 Quote Hides

The cost of a radiant Cut Lab Grown Diamond in the USD 150-1225 band splits roughly as below. The line buyers challenge most is labor, and it is the line that decides whether the piece survives a season.

Cost lineShareWhat moves it
Base metal or alloy for radiant Cut Lab Grown Diamond34%Alloy choice and casting yield
Stone or melee for radiant Cut Lab Grown Diamond25%Sieve range and lot batching
Setting and finishing labor for radiant Cut Lab Grown Diamond22%Jig design and bench minutes
Plating, polish and QC for radiant Cut Lab Grown Diamond15%Per-tray versus per-piece checks
Packaging for radiant Cut Lab Grown Diamond4%single-piece foam box

If a supplier will not break out the five lines above, the number you are comparing is not a price. It is a total that somebody else assembled from assumptions, shipped as single-piece foam box and certified IGI report, on a 50-piece Made to Order order at USD 150-1225.

What a Report Proves and What It Does Not

Nobody quotes it for radiant Cut Lab Grown Diamond until something goes wrong, which is exactly why it belongs in the first email, certified IGI report and packed single-piece foam box at 50 pieces.

Three numbers decide it for radiant 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

We send a one-page sheet with every radiant 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

The Sample Approval That Survives Production

It is not a marketing point on radiant Cut Lab Grown Diamond. It is the number that decides whether the second order happens, 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 radiant Cut Lab Grown Diamond and letting the buyer discover the spread. It works once. The second order goes to whichever supplier quoted honestly, the figure being USD 150-1225 for a 50-piece run.

We would rather lose a first order of radiant 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, certified IGI report and packed single-piece foam box at 50 pieces.

A 50-Piece Test Run

At 50 pieces inside single-piece foam box, the first order reads sell-through without betting the season on one model, and the Made to Order quote for it sits at USD 150-1225.

Buyers who run that measurement before committing a season usually keep the supplier. Buyers who skip it usually pay twice for the same lesson, and 50 pieces leaves Wuzhou in single-piece foam box at USD 150-1225.

The Dock Check on radiant Cut Lab Grown Diamond

We ship from Guangzhou or Shenzhen and pick the port on the carrier rate, not on habit. IGI report travels with the shipping documents, priced at USD 150-1225 for the 50-piece Made to Order run.

DDP removes the duty invoice that arrives after the carton clears, which matters on a first Made to Order order at USD 150-1225.

Three steps at the dock: count against the packing list, weigh a sample tray, measure ten pieces. None needs a lab, priced at USD 150-1225 for the 50-piece Made to Order run.

From Spec to single-piece foam box

The calendar below is what we quote on a 50-piece Made to Order run of radiant Cut Lab Grown Diamond. It starts when the spec is signed, not when the deposit clears, priced at USD 150-1225 for the 50-piece Made to Order run.

  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.

A first order of 50 pieces is a measurement, not a purchase. It tells you what report plot match looks like from this bench, 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, which the Made to Order file records at USD 150-1225 in single-piece foam box.

How long does a reorder of the same radiant 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, priced at USD 150-1225 for the 50-piece Made to Order run.

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

Rhodium at 0.20 micron minimum on white radiant 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, priced at USD 150-1225 for the 50-piece Made to Order run.

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

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, which the Made to Order file records at USD 150-1225 in single-piece foam box.
