Lab Grown Diamond Gold Made to Order: Carton Cube, Duty and the Freight Line That Sur - HOLYCOME

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

Lab Grown Diamond Gold Made to Order: Carton Cube, Duty and the Freight Line That Sur - HOLYCOME

Why the Made to Order Quote Looks Cheap Until It Lands

Two buyers ordered the same lab Grown Diamond Gold in the same month. One paid 9% less and absorbed 23 rejects out of 50 pieces; the other paid our quote and shipped clean. The difference was certificate mismatch, and it was measurable on both benches, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

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, quoted at USD 150-1225 per piece in single-piece foam box.

The Made-to-Order Path for lab Grown Diamond Gold

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

Twenty days is realistic for a new lab Grown Diamond Gold 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, quoted at USD 150-1225 per piece in single-piece foam box.

What Fails First on lab Grown Diamond Gold

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

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

In a 50-piece run this typically shows on 8 of pieces. Catching it means measuring report plot match at the tray level, not inspecting the finished carton, with IGI report and single-piece foam box stated on the same sheet.

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

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, 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

None of these are premium features. They cost seconds per piece and they remove the reason a buyer has to inspect twice, and the Made to Order quote for it sits at USD 150-1225.

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, certified IGI report and packed single-piece foam box at 50 pieces.

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

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 USD 150-1225 on the Made to Order schedule.

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

What a USD 150-1225 Quote Hides

The cost of a lab Grown Diamond Gold 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 lab Grown Diamond Gold34%Alloy choice and casting yield
Stone or melee for lab Grown Diamond Gold25%Sieve range and lot batching
Setting and finishing labor for lab Grown Diamond Gold22%Jig design and bench minutes
Plating, polish and QC for lab Grown Diamond Gold15%Per-tray versus per-piece checks
Packaging for lab Grown Diamond Gold4%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, which is how the Made to Order account reads it at USD 150-1225.

What a Report Proves and What It Does Not

On lab Grown Diamond Gold, the difference between a 40-day order and a 90-day order is usually two signatures, not a factory delay, certified IGI report and packed single-piece foam box at 50 pieces.

Three numbers decide it for lab Grown Diamond Gold: 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 how the Made to Order account reads it at USD 150-1225.

We send a one-page sheet with every lab Grown Diamond Gold 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 the Made to Order file records at USD 150-1225 in single-piece foam box.

The Sample Approval That Survives Production

Buyers in US wholesale tend to over-index on unit price for lab Grown Diamond Gold and under-index on what happens after delivery, shipped as single-piece foam box and certified IGI report.

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

We would rather lose a first order of lab Grown Diamond Gold 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 at USD 150-1225 for 50 pieces that is the number the buyer signs.

Buyers who run that measurement before committing a season usually keep the supplier. Buyers who skip it usually pay twice for the same lesson, which is USD 150-1225 on the Made to Order schedule.

The Dock Check on lab Grown Diamond Gold

We ship from Guangzhou or Shenzhen and pick the port on the carrier rate, not on habit. IGI report travels with the shipping documents, shipped as single-piece foam box and certified IGI report.

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, shipped as single-piece foam box and certified IGI report, quoted at USD 150-1225 per piece in single-piece foam box.

From Spec to single-piece foam box

The calendar below is what we quote on a 50-piece Made to Order run of lab Grown Diamond Gold. It starts when the spec is signed, not when the deposit clears, with IGI report and single-piece foam box stated on the same sheet.

  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, quoted at USD 150-1225 per piece in single-piece foam box.

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

How long does a reorder of the same lab Grown Diamond Gold 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, shipped as single-piece foam box and certified IGI report.

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

Rhodium at 0.20 micron minimum on white lab Grown Diamond Gold, 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, the figure being USD 150-1225 for a 50-piece run.

How is lab Grown Diamond Gold 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, which is how the Made to Order account reads it at USD 150-1225.

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