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

Why the Made to Order Quote Looks Cheap Until It Lands

Two buyers ordered the same lab Grown Diamond Earring 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, with IGI report and single-piece foam box stated on the same sheet.

In the Made to Order file the failure was already written down. Certificate mismatch sat in the buyer's own incoming report from the previous season and nobody carried it forward, so the same line failed twice, the figure being USD 150-1225 for a 50-piece run.

The second run shipped single-piece foam box with the spec stapled to the packing list. Zero rejects on arrival, and the buyer's own bench stopped re-inspecting, which is USD 150-1225 on the Made to Order schedule.

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

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

Twenty days is realistic for a new lab Grown Diamond Earring 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, shipped as single-piece foam box and certified IGI report.

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

What Fails First on lab Grown Diamond Earrings

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 50 pieces leaves Wuzhou in single-piece foam box 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 how the Made to Order account reads it 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, certified IGI report and packed single-piece foam box at 50 pieces.

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

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

The Measurements Behind a USD 150-1225 Quote

Specification is the only part of a lab Grown Diamond Earrings quote that survives the season. These four measurements are what we write into the single-piece foam box paperwork, and 50 pieces leaves Wuzhou in single-piece foam box 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

Every line above is measurable with a gauge and a scale. At USD 150-1225 per piece, a supplier who cannot state them is selling a photo.

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

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 the Made to Order quote for it sits 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

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

What a USD 150-1225 Quote Hides

The 50-piece Made to Order price splits as below. The line that decides season two is the plating and QC share, not the metal, with IGI report and single-piece foam box stated on the same sheet.

Cost lineShareWhat moves it
Base metal or alloy for lab Grown Diamond Earrings34%Alloy choice and casting yield
Stone or melee for lab Grown Diamond Earrings25%Sieve range and lot batching
Setting and finishing labor for lab Grown Diamond Earrings22%Jig design and bench minutes
Plating, polish and QC for lab Grown Diamond Earrings15%Per-tray versus per-piece checks
Packaging for lab Grown Diamond Earrings4%single-piece foam box

Five lines, one price. If the supplier will not break them out, the number being compared is not a lab Grown Diamond Earrings price, and 50 pieces leaves Wuzhou in single-piece foam box at USD 150-1225.

What a Report Proves and What It Does Not

In US e-commerce, this is the single most negotiated line on lab Grown Diamond Earrings and the least documented one, priced at USD 150-1225 for the 50-piece Made to Order run.

Three numbers decide it for lab Grown Diamond Earrings: 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, with IGI report and single-piece foam box stated on the same sheet.

We send a one-page sheet with every lab Grown Diamond Earrings 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, with IGI report and single-piece foam box stated on the same sheet.

The Sample Approval That Survives Production

Nobody quotes it for lab Grown Diamond Earrings until something goes wrong, which is exactly why it belongs in the first email, the figure being USD 150-1225 for a 50-piece run.

There is a version of this that looks cheaper on paper and costs more in practice: quoting the best case on lab Grown Diamond Earrings and letting the buyer discover the spread. It works once. The second order goes to whichever supplier quoted honestly, shipped as single-piece foam box and certified IGI report.

We would rather lose a first order of lab Grown Diamond Earrings 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, which is how the Made to Order account reads it at USD 150-1225.

A 50-Piece Test Run

The first order should be small enough to inspect completely and large enough to keep the gauge check independent of the shift, shipped as single-piece foam box and certified IGI report, which is how the Made to Order account reads it at USD 150-1225.

Put the reject rule in writing before the deposit. The Made to Order conversation after arrival is shorter when the rule is on the order already, which the Made to Order file records at USD 150-1225 in single-piece foam box.

The Dock Check on lab Grown Diamond Earrings

We ship from Guangzhou or Shenzhen, and the port choice follows the carrier rate rather than a fixed habit, quoted at USD 150-1225 per piece in single-piece foam box.

DDP suits a first Made to Order order because the duty invoice arrives after the carton clears, and that is the line buyers forget to budget, priced at USD 150-1225 for the 50-piece Made to Order run.

The arrival check is three steps and none needs a lab: count against the packing list, weigh a sample, measure ten pieces, the figure being USD 150-1225 for a 50-piece run.

From Spec to single-piece foam box

Our process is deliberately boring, because boring is what survives a bulk run with several sets of hands on it, which is how the Made to Order account reads it at USD 150-1225.

  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 at 50 pieces per design is a measurement rather than a purchase. It tells you what report plot match and table percentage within the stated band looks like from this line, which the Made to Order file records at USD 150-1225 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, on a 50-piece Made to Order order at USD 150-1225.

How long does a reorder of the same lab Grown Diamond Earring 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, the figure being USD 150-1225 for a 50-piece run.

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

Rhodium at 0.20 micron minimum on white lab Grown Diamond Earrings, 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, and at USD 150-1225 for 50 pieces that is the number the buyer signs.

How is lab Grown Diamond Earrings 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 50 pieces leaves Wuzhou in single-piece foam box 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, on a 50-piece Made to Order order at USD 150-1225.
