Lab Grown Diamond Silver Valentine Program: AQL, Tray Checks and What a QC Report Sho - HOLYCOME

Why the Valentine Program Quote Looks Cheap Until It Lands

Two buyers ordered the same lab Grown Diamond Silver 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, shipped as heart gift box and certified IGI report.

Nothing in that rejection was exotic. At USD 134-1097 per piece and 300 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 300 pieces that is a few hours at the bench and the whole claim file disappears, which is how the Valentine Program account reads it at USD 134-1097.

The Measurements Behind a USD 134-1097 Quote

Four numbers separate a 300-piece run that clears inspection from one that generates a credit note. None of them appears on the sample photo, priced at USD 134-1097 for the 300-piece Valentine Program run.

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

None of these are premium features. They cost seconds per piece and they remove the reason a buyer has to inspect twice, which is how the Valentine Program account reads it at USD 134-1097.

What a USD 134-1097 Quote Hides

The cost of a lab Grown Diamond Silver in the USD 134-1097 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.

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, quoted at USD 134-1097 per piece 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, shipped as heart gift box and certified IGI report.

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, quoted at USD 134-1097 per piece 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, with IGI report and heart gift box stated on the same sheet.

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

What Fails First on lab Grown Diamond Silver

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, with IGI report and heart gift box stated on the same sheet.

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, certified IGI report and packed heart gift box at 300 pieces.

growth-method disclosure

CVD and HPHT stones behave differently under high heat during setting. Disclosing the method protects both sides in a repair claim, quoted at USD 134-1097 per piece in heart gift box.

In a 300-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 how the Valentine Program account reads it at USD 134-1097.

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, and at USD 134-1097 for 300 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, and at USD 134-1097 for 300 pieces that is the number the buyer signs.

AQL, Tray Checks and What a QC Report Should Say

In the US market, this is the single most negotiated line on lab Grown Diamond Silver and the least documented one, and the Valentine Program quote for it sits at USD 134-1097.

At 300 pieces the arithmetic on lab Grown Diamond Silver 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, which the Valentine Program file records at USD 134-1097 in heart gift box.

We quote both a first-run price and a reorder price for lab Grown Diamond Silver on the same sheet so the buyer can see where the curve flattens. Most flatten by the third run, certified IGI report and packed heart gift box at 300 pieces.

Carton Cube, Duty and the Freight Line That Surprises Buyers

Nobody quotes it for lab Grown Diamond Silver until something goes wrong, which is exactly why it belongs in the first email, and at USD 134-1097 for 300 pieces that is the number the buyer signs.

One practical note on timing for lab Grown Diamond Silver: 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, priced at USD 134-1097 for the 300-piece Valentine Program run.

We date the lab Grown Diamond Silver proforma from signature for that reason, and we state the deposit deadline in the same email that carries the spec sheet, the figure being USD 134-1097 for a 300-piece run.

Valentine Window for lab Grown Diamond Silver

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, and the Valentine Program quote for it sits at USD 134-1097.

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

Photography has to be red-and-white neutral. A lab Grown Diamond Silver 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, on a 300-piece Valentine Program order at USD 134-1097.

From Spec to heart gift box

The calendar below is what we quote on a 300-piece Valentine Program run of lab Grown Diamond Silver. It starts when the spec is signed, not when the deposit clears, which is USD 134-1097 on the Valentine Program schedule.

  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 of 50 pieces is a measurement, not a purchase. It tells you what report plot match looks like from this bench, the figure being USD 134-1097 for a 300-piece run.

A 300-Piece Test Run

At 300 pieces inside heart gift box, the first order reads sell-through without betting the season on one model, which the Valentine Program file records at USD 134-1097 in heart gift box.

Buyers who run that measurement before committing a season usually keep the supplier. Buyers who skip it usually pay twice for the same lesson, with IGI report and heart gift box stated on the same sheet, and at USD 134-1097 for 300 pieces that is the number the buyer signs.

The Dock Check on lab Grown Diamond Silver

We ship from Guangzhou or Shenzhen and pick the port on the carrier rate, not on habit. IGI report travels with the shipping documents, which is USD 134-1097 on the Valentine Program schedule.

DDP removes the duty invoice that arrives after the carton clears, which matters on a first Valentine Program order at USD 134-1097.

Three steps at the dock: count against the packing list, weigh a sample tray, measure ten pieces. None needs a lab, which is USD 134-1097 on the Valentine Program schedule.

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, priced at USD 134-1097 for the 300-piece Valentine Program run.

What is the minimum order for lab Grown Diamond Silver?

50 pieces per lab Grown Diamond Silver. 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 lab Grown Diamond Silver?

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