Loose Lab Grown Gemstones Valentine Program: AQL, Tray Checks and What a QC Report Sh - HOLYCOME
Loose Lab Grown Gemstones: tolerances, cost structure and the reject rule for US wholesale buyers.
Why the Valentine Program Quote Looks Cheap Until It Lands
In February, a US buyer of loose Lab Grown Gemstones ordered 300 loose Lab Grown Gemstones and asked for the same calibrated sizes from 1.5 mm to 12 mm as a competitor's sample. What arrived matched the photo and missed the drawing, and 13 pieces had to be reworked at the buyer's expense, with IGI report and heart gift box stated on the same sheet.
The defect did not surprise us. Sieve drift is the predictable output of a run where nobody wrote the tolerance down, and it is the first measurement we take on an incoming loose Lab Grown Gemstone, with IGI report and heart gift box stated on the same sheet, priced at USD 3-106 for the 300-piece Valentine Program run.
We did not discount the quote. We changed the gauge, the seat cut, the plating log and the tray rule, and the second run shipped with zero rejects on size distribution within the declared sieve and zero girdle chips on arrival, priced at USD 3-106 for the 300-piece Valentine Program run.
The Measurements Behind a USD 3-106 Quote
Price is the first thing compared and the last thing that matters. These four measurements decide the return rate on loose Lab Grown Gemstones, and three of them cost nothing to specify, and the Valentine Program quote for it sits at USD 3-106.
| Spec point | Common trade output | HOLYCOME standard | Cost if missed |
|---|---|---|---|
| Hallmark depth and placement | Stamped where it fits | Fixed position, depth measured so it never breaks the shank | Customs query and remaking |
| Solder flow at the joint | Not inspected | Joint inspected under 10x before setting | Crack at the seam in transit |
| Plating thickness | Nominal only | 0.20 micron rhodium logged per lot, 3 microns on vermeil | Wear-through inside one season |
| Surface porosity after polish | Seen after plating | Cast porosity checked before plating, rejects pulled at that stage | Plating blister six weeks later |
Each line is a gauge, not a slogan. A supplier who cannot quote a number for sieve drift is quoting an opinion about loose Lab Grown Gemstones, and 300 pieces leaves Wuzhou in heart gift box at USD 3-106.
What a USD 3-106 Quote Hides
The Valentine Program price of 300 pieces splits as below. The line buyers challenge is labor, and it is the line that decides the second season, which is USD 3-106 on the Valentine Program schedule.
| Cost line | Share | What moves it |
|---|---|---|
| Base metal or alloy for loose Lab Grown Gemstones | 34% | Alloy choice and casting yield |
| Stone or melee for loose Lab Grown Gemstones | 25% | Sieve range and lot batching |
| Setting and finishing labor for loose Lab Grown Gemstones | 22% | Jig design and bench minutes |
| Plating, polish and QC for loose Lab Grown Gemstones | 15% | Per-tray versus per-piece checks |
| Packaging for loose Lab Grown Gemstones | 4% | heart gift box |
Break the USD 3-106 quote into these five lines and the comparison stops being rhetorical.
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 3-106 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 3-106 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 3-106 in heart gift box.
Certification is IGI report for the lots that carry it, with a batch report and per-piece measurement of size distribution within the declared sieve 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 the Valentine Program file records at USD 3-106 in heart gift box.
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 3-106 on the Valentine Program schedule.
What Fails First on loose Lab Grown Gemstones
sieve drift
A parcel sold as 2.0-2.2 mm with 15% of stones at 1.9 mm changes the setting labor on the buyer's bench. Sieve the parcel, do not sample it, certified IGI report and packed heart gift box at 300 pieces.
Our countermeasure is a gauge and a written limit. It adds about 6 seconds per piece and removes the defect from the run rather than from the carton, priced at USD 3-106 for the 300-piece Valentine Program run.
mixed color lots
Mixing near-colorless and G-H stones in one parcel produces a finished piece with a visible tonal step. Parcels ship by single lot, the figure being USD 3-106 for a 300-piece run.
In a 300-piece run this typically shows on 17 of pieces. Catching it means measuring size distribution within the declared sieve at the tray level, not inspecting the finished carton, priced at USD 3-106 for the 300-piece Valentine Program run.
girdle damage
Stones packed loose in a bag chip each other in transit. Individually wrapped parcels cost more and arrive usable, and 300 pieces leaves Wuzhou in heart gift box at USD 3-106.
The commercial effect is replacement stones plus a sorting delay on the buyer's line. 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 3-106 for a 300-piece run.
AQL, Tray Checks and What a QC Report Should Say
Buyers in US e-commerce tend to over-index on unit price for loose Lab Grown Gemstones and under-index on what happens after delivery, and the Valentine Program quote for it sits at USD 3-106.
At 300 pieces the arithmetic on loose Lab Grown Gemstones 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, quoted at USD 3-106 per piece in heart gift box.
We quote both a first-run price and a reorder price for loose Lab Grown Gemstones on the same sheet so the buyer can see where the curve flattens. Most flatten by the third run, and the Valentine Program quote for it sits at USD 3-106.
Carton Cube, Duty and the Freight Line That Surprises Buyers
This is where loose Lab Grown Gemstones stops being a commodity and starts being a supply relationship, and 300 pieces leaves Wuzhou in heart gift box at USD 3-106.
One practical note on timing for loose Lab Grown Gemstones: 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, which is USD 3-106 on the Valentine Program schedule.
We date the loose Lab Grown Gemstones proforma from signature for that reason, and we state the deposit deadline in the same email that carries the spec sheet, on a 300-piece Valentine Program order at USD 3-106.
Valentine Window for loose Lab Grown Gemstones
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 3-106 for the 300-piece Valentine Program run.
Paired designs move better than single pieces here. A matching pair of loose Lab Grown Gemstones, boxed together with two cards, converts at the same retail price as two singles and costs about nine percent more to make, shipped as heart gift box and certified IGI report.
Photography has to be red-and-white neutral. A loose Lab Grown Gemstone 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, certified IGI report and packed heart gift box at 300 pieces.
From Spec to heart gift box
On 300 pieces of loose Lab Grown Gemstones the calendar starts at the signed spec, not at the deposit, and it ends with heart gift box on a pallet, and the Valentine Program quote for it sits at USD 3-106.
- Lock the spec: metal, stone size range, plating thickness, sizing band and finish, all written on one sheet.
- Pull a stock-component sample in 3-5 days and measure it against that sheet, not against the photo.
- Approve the sample in writing, including the reject rule and the retained reference tray.
- Run bulk in 15-20 days for orders under 500 pieces, with the gauge check independent of the shift.
- Ship from Guangzhou or Shenzhen with the QC sheet in the carton and the batch report by email.
A 50-piece first order at USD 3-106 is a measurement of size distribution within the declared sieve, not a commitment to the range.
A 300-Piece Test Run
A test run at 50 pieces tells you three things: whether sieve drift is controlled, whether packing survives freight, and whether the count is honest, which is USD 3-106 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 already on the order, with IGI report and heart gift box stated on the same sheet.
The Dock Check on loose Lab Grown Gemstones
Air lands in 5-8 days to the US west coast and sea takes three times the transit. At USD 3-106 per piece the choice is a cash-flow decision.
DDP is available for US accounts that want duty and clearance on our side, and it removes the invoice that arrives after the carton clears, shipped as heart gift box and certified IGI report, which is how the Valentine Program account reads it at USD 3-106.
On arrival, weigh a tray and measure ten pieces. Anything outside the band is a claim with evidence rather than a difference of opinion, and at USD 3-106 for 300 pieces that is the number the buyer signs.

50 pieces per loose Lab Grown Gemstone. 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 3-106 in heart gift box.
