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

Round Cut Lab Grown Diamond Distributor Tier: What the Quote Actually Covers - HOLYCOME

What the Quote Actually Covers

Last April, a US buyer of round Cut Lab Grown Diamond placed 800 round Cut Lab Grown Diamond against a sample signed in August. The first container landed with 9 pieces that failed on certificate mismatch alone, and USD 45-230 landed on the buyer's P&L before a single unit sold, certified SGS batch report and packed bulk carton, 50 per bag at 800 pieces.

Nobody on that bench was careless. They were working to a spec that existed only in a photograph, and certificate mismatch is what a photograph fails to define, which the Distributor Tier file records at USD 114-931 in bulk carton, 50 per bag.

The fix cost about 26 seconds per round Cut Lab Grown Diamond and removed the credit note entirely. That is the whole economics of a spec sheet, and it is why we write one on every quote, quoted at USD 114-931 per piece in bulk carton, 50 per bag.

Where USD 114-931 Per Piece Actually Goes

Cost per piece at USD 114-931 leaves little room for assumption. The table shows which line compresses and which one only moves quality.

Cost lineShareWhat moves it
Base metal or alloy for round Cut Lab Grown Diamond30%Alloy choice and casting yield
Stone or melee for round Cut Lab Grown Diamond20%Sieve range and lot batching
Setting and finishing labor for round Cut Lab Grown Diamond19%Jig design and bench minutes
Plating, polish and QC for round Cut Lab Grown Diamond12%Per-tray versus per-piece checks
Packaging for round Cut Lab Grown Diamond19%bulk carton, 50 per bag

A factory with no bench minutes per piece has never costed round Cut Lab Grown Diamond at USD 114-931. Ask for minutes and for the reject rule.

What US buyers Check Before They Sign

Four lines decide whether round Cut Lab Grown Diamond at USD 114-931 sells through or comes back, and none of them appears on a typical trading-company quote.

Put these four into the purchase order and the Distributor Tier argument after delivery becomes arithmetic, quoted at USD 114-931 per piece in bulk carton, 50 per bag.

Distributor Pricing Tiers on round Cut Lab Grown Diamond

A distributor does not buy a round Cut Lab Grown Diamond, they buy a position. Tier pricing is quoted against annual volume with a floor per SKU, and the tier is reviewed on shipped units rather than on forecast, with SGS batch report and bulk carton, 50 per bag stated on the same sheet.

What the tier buys is protection: a defined territory, a no-direct-sell clause inside that territory, and a first look at new models for one season. Without those three lines the discount is just a lower price and the distributor will not hold stock for you, shipped as bulk carton, 50 per bag and certified SGS batch report.

Turn is the number the distributor manages. At USD 114-931 per piece and a 45-day turn, the margin per shelf foot is thin. That is why bulk orders of round Cut Lab Grown Diamond move in 800-piece lots rather than in the 50-piece sample quantity.

The Three Failures We See Most in Incoming Samples

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 how the Distributor Tier account reads it at USD 114-931.

In a 800-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 Distributor Tier account reads it at USD 114-931.

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 at USD 114-931 for 800 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, priced at USD 114-931 for the 800-piece Distributor Tier run.

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, priced at USD 114-931 for the 800-piece Distributor Tier run.

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 USD 114-931 on the Distributor Tier schedule.

Order Terms, Sample Timing and Packing

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 800-piece Distributor Tier 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, which the Distributor Tier file records at USD 114-931 in bulk carton, 50 per bag.

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 114-931 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 bulk carton, 50 per bag format at 800 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 Distributor Tier quote for it sits at USD 114-931.

Certification is SGS batch 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, priced at USD 114-931 for the 800-piece Distributor Tier run.

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 800 pieces leaves Wuzhou in bulk carton, 50 per bag at USD 114-931.

Sample to Container: The Real Calendar

Buyers who have run three programs on round Cut Lab Grown Diamond know this instinctively; first-time buyers learn it the expensive way, which the Distributor Tier file records at USD 114-931 in bulk carton, 50 per bag.

One practical note on timing for round 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 800 pieces leaves Wuzhou in bulk carton, 50 per bag at USD 114-931.

We date the round 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, with SGS batch report and bulk carton, 50 per bag stated on the same sheet.

AQL, Tray Checks and What a QC Report Should Say

The short version for round Cut Lab Grown Diamond: it is arithmetic, not relationship. The long version is below, quoted at USD 114-931 per piece in bulk carton, 50 per bag.

In US wholesale terms, this is the difference between a landed cost the buyer can plan against and a number that moves after the container ships. For round Cut Lab Grown Diamond, we publish the figure per SKU and hold it for the order window rather than for the calendar year, and the Distributor Tier quote for it sits at USD 114-931.

Practically, it shows up in three places for round Cut Lab Grown Diamond: the proforma, the QC sheet and the credit note if something goes wrong. All three should quote the same number. When they do not, the argument is about paperwork, not about the product, priced at USD 114-931 for the 800-piece Distributor Tier run.

How a Repeat Order Gets Built

The sequence below is fixed for a Distributor Tier run. The dates move with the stone lot, not with the shipping season, and the Distributor Tier quote for it sits at USD 114-931.

  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.

Reorders inside this sequence run 12-15 days, because the model and the gauge set stay here after the Distributor Tier shipment, and the Distributor Tier quote for it sits at USD 114-931.

Freight, Duty and the Arrival Check

Export runs through Guangzhou or Shenzhen. Air freight lands in 5-8 days on the US west coast and 7-10 on the east, with SGS batch report and bulk carton, 50 per bag stated on the same sheet, priced at USD 114-931 for the 800-piece Distributor Tier run.

For a first order, DDP matters more than the freight rate. The surprise is the duty line, not the per-kilo charge, priced at USD 114-931 for the 800-piece Distributor Tier run.

Check the count, the weight and report plot match and table percentage within the stated band before the carton goes to the shelf. Twenty minutes at receiving saves a season of returns, and the Distributor Tier quote for it sits at USD 114-931.

What This Means for a First Order

A first Distributor Tier order of 50 pieces per design at USD 114-931 is a test of the line, not a commitment to the range.

Ask for the retained tray and the batch report with the first shipment. Both are free and both decide the second order, which is how the Distributor Tier account reads it at USD 114-931.

Frequently Asked Questions

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

Rhodium at 0.20 micron minimum on white round 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, which is how the Distributor Tier account reads it at USD 114-931.

How is round Cut Lab Grown Diamond packed for bulk carton, 50 per bag?

Every unit goes into a foam-backed pouch, then the bulk carton, 50 per bag, then the outer carton at 800 pieces. The packing list carries the SKU, the size and the stone size so receiving can check without opening every box, priced at USD 114-931 for the 800-piece Distributor Tier run.

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, quoted at USD 114-931 per piece in bulk carton, 50 per bag.

How long does a reorder of the same round 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, and the Distributor Tier quote for it sits at USD 114-931.

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

Rhodium at 0.20 micron minimum on white round 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, which is how the Distributor Tier account reads it at USD 114-931.
