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

Radiant Cut Lab Grown Diamond Valentine Program: AQL, Tray Checks and What a QC Repor - HOLYCOME

Why the Valentine Program Quote Looks Cheap Until It Lands

Two buyers ordered the same radiant Cut Lab Grown Diamond in the same month. One paid 9% less and absorbed 23 rejects out of 300 pieces; the other paid our quote and shipped clean. The difference was certificate mismatch, and it was measurable on both benches, certified IGI report and packed heart gift box at 300 pieces.

In the Valentine Program 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, certified IGI report and packed heart gift box at 300 pieces.

The second run shipped heart gift box with the spec stapled to the packing list. Zero rejects on arrival, and the buyer's own bench stopped re-inspecting, which the Valentine Program file records at USD 134-1097 in heart gift box.

The Measurements Behind a USD 134-1097 Quote

Specification is the only part of a radiant Cut Lab Grown Diamond quote that survives the season. These four measurements are what we write into the heart gift box paperwork, which is USD 134-1097 on the Valentine Program schedule.

Spec pointCommon trade outputHOLYCOME standardCost if missed
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
Plating thicknessNominal only0.20 micron rhodium logged per lot, 3 microns on vermeilWear-through inside one season
Surface porosity after polishSeen after platingCast porosity checked before plating, rejects pulled at that stagePlating blister six weeks later

Every line above is measurable with a gauge and a scale. At USD 134-1097 per piece, a supplier who cannot state them is selling a photo.

What a USD 134-1097 Quote Hides

The 300-piece Valentine Program price splits as below. The line that decides season two is the plating and QC share, not the metal, which is USD 134-1097 on the Valentine Program schedule.

Five lines, one price. If the supplier will not break them out, the number being compared is not a radiant Cut Lab Grown Diamond price, which the Valentine Program file records at USD 134-1097 in heart gift 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 300-piece Valentine Program 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, the figure being USD 134-1097 for a 300-piece 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 134-1097 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 heart gift box format at 300 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, which the Valentine Program file records at USD 134-1097 in heart gift box.

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, on a 300-piece Valentine Program order at USD 134-1097.

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 USD 134-1097 on the Valentine Program schedule.

What Fails First on radiant Cut Lab Grown Diamond

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, on a 300-piece Valentine Program order at USD 134-1097.

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, quoted at USD 134-1097 per piece in heart gift box.

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 the Valentine Program file records at USD 134-1097 in heart gift box.

In a 300-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, shipped as heart gift box and certified IGI report.

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, shipped as heart gift box and certified IGI report.

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, shipped as heart gift box and certified IGI report.

AQL, Tray Checks and What a QC Report Should Say

This is where radiant Cut Lab Grown Diamond stops being a commodity and starts being a supply relationship, which the Valentine Program file records at USD 134-1097 in heart gift box.

At 300 pieces the arithmetic on radiant Cut Lab Grown Diamond changes: the fixed costs spread, the variable costs do not. That is why the second order prices better than the first even when the gold fix has moved up, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.

We quote both a first-run price and a reorder price for radiant Cut Lab Grown Diamond on the same sheet so the buyer can see where the curve flattens. Most flatten by the third run, and at USD 134-1097 for 300 pieces that is the number the buyer signs.

Carton Cube, Duty and the Freight Line That Surprises Buyers

The figure below is what we quote for radiant Cut Lab Grown Diamond, and it is deliberately narrower than the market average, quoted at USD 134-1097 per piece in heart gift box.

One practical note on timing for radiant Cut Lab Grown Diamond: the calendar starts when the spec is signed, not when the deposit clears. A buyer who signs in week one and pays in week three gets the goods in week five, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.

We date the radiant Cut Lab Grown Diamond proforma from signature for that reason, and we state the deposit deadline in the same email that carries the spec sheet, shipped as heart gift box and certified IGI report.

Valentine Window for radiant Cut Lab Grown Diamond

The Valentine window is short and unforgiving: stock has to be in the warehouse by the last week of January or the season is gone. That puts the production order in the second week of December, ahead of the Lunar New Year slowdown, priced at USD 134-1097 for the 300-piece Valentine Program run.

Paired designs move better than single pieces here. A matching pair of radiant Cut Lab Grown Diamond, boxed together with two cards, converts at the same retail price as two singles and costs about nine percent more to make, priced at USD 134-1097 for the 300-piece Valentine Program run.

Photography has to be red-and-white neutral. A radiant Cut Lab Grown Diamond shot on a red silk background reads as a gift in a listing thumbnail, and that is the only image most buyers will ever see, which the Valentine Program file records at USD 134-1097 in heart gift box.

From Spec to heart gift box

Our process is deliberately boring, because boring is what survives a bulk run with several sets of hands on it, quoted at USD 134-1097 per piece in heart gift box.

  1. Lock the spec: metal, stone size range, plating thickness, sizing band and finish, all written on one sheet.
  2. Pull a stock-component sample in 3-5 days and measure it against that sheet, not against the photo.
  3. Approve the sample in writing, including the reject rule and the retained reference tray.
  4. Run bulk in 15-20 days for orders under 500 pieces, with the gauge check independent of the shift.
  5. Ship from Guangzhou or Shenzhen with the QC sheet in the carton and the batch report by email.

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, certified IGI report and packed heart gift box at 300 pieces, and the Valentine Program quote for it sits at USD 134-1097.

A 300-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, which is USD 134-1097 on the Valentine Program schedule.

Put the reject rule in writing before the deposit. The Valentine Program conversation after arrival is shorter when the rule is on the order already, priced at USD 134-1097 for the 300-piece Valentine Program run.

The Dock Check on radiant Cut Lab Grown Diamond

We ship from Guangzhou or Shenzhen, and the port choice follows the carrier rate rather than a fixed habit, the figure being USD 134-1097 for a 300-piece run.

DDP suits a first Valentine Program order because the duty invoice arrives after the carton clears, and that is the line buyers forget to budget, on a 300-piece Valentine Program order at USD 134-1097.

The arrival check is three steps and none needs a lab: count against the packing list, weigh a sample, measure ten pieces, and at USD 134-1097 for 300 pieces that is the number the buyer signs.

Frequently Asked Questions

What are the payment terms?

30 percent deposit with the order, 70 percent against the bill of lading. For accounts on a second order we quote 30/70 with a 15-day balance window once the first shipment has cleared, with IGI report and heart gift box stated on the same sheet.

What is the minimum order for radiant Cut Lab Grown Diamond?

50 pieces per radiant Cut Lab Grown Diamond. Designs mix inside one shipment, so a first order of three designs at 50 pieces each is normal for a new US account. Below 50 the gauge check stops being independent of the shift, which the Valentine Program file records at USD 134-1097 in heart gift box.

Do you supply certificates for radiant Cut Lab Grown Diamond?

IGI report on radiant Cut Lab Grown Diamond above the threshold stated on the quote. Below it we supply a batch report plus per-piece measurement of report plot match, which is what a counter or a listing actually needs, and 300 pieces leaves Wuzhou in heart gift box at USD 134-1097.

How do you handle a rejected tray?

We replace or credit inside the same order cycle. The retained reference tray decides: if certificate mismatch shows on our retained piece we own it, and if it appeared in transit we split the assay cost and file with the carrier, which the Valentine Program file records at USD 134-1097 in heart gift box.

What are the payment terms?

30 percent deposit with the order, 70 percent against the bill of lading. For accounts on a second order we quote 30/70 with a 15-day balance window once the first shipment has cleared, with IGI report and heart gift box stated on the same sheet.
