Loose Lab Grown Diamond Stones, Calibrated by Shape Vermeil Upgrade: What a Report Pr - HOLYCOME
Loose Lab Grown Diamond Stones, Calibrated by Shape: tolerances, cost structure and the reject rule for US wholesale buyers.
Vermeil and Gold Plating Specs for loose Lab Grown Diamond Stones, Calibrated by Shape
Vermeil means a gold layer of at least 2.5 microns over sterling silver, and the US market reads that number as a material claim rather than a finish note. Below 2.5 microns the piece is gold-plated, not vermeil, and the word cannot be used, on a 100-piece Vermeil Upgrade order at USD 4-152.
We run 3 microns on loose Lab Grown Diamond Stones, Calibrated by Shape for accounts that publish the claim, with a palladium strike layer so wear-through reads white and not yellow. Thickness is logged per lot and appears on the GRA report batch sheet, priced at USD 4-152 for the 100-piece Vermeil Upgrade run.
The cost difference is real: the USD 4-152 band moves up roughly sixty percent against rhodium-finished silver, and the retail price has to carry that or the margin disappears in the second season when the plating shows wear.
What a Report Proves and What It Does Not
Last June, a US buyer of loose Lab Grown Diamond Stones, Calibrated by Shape placed 100 loose Lab Grown Diamond Stones, Calibrated by Shape against a sample signed in October. The first container landed with 9 pieces that failed on sieve drift alone, and USD 5-40 landed on the buyer's P&L before a single unit sold, which is how the Vermeil Upgrade account reads it at USD 4-152.
On a 100-piece order at USD 4-152, a sieve drift rate above two percent is not a quality surprise. It is a costing error that shows up as a credit note three weeks later.
Nothing in the rebuild was expensive. A gauge, a written limit and a retained tray did the work that a discount would only have delayed, and the Vermeil Upgrade quote for it sits at USD 4-152.
The Three Failures We See Most in Incoming Samples
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, the figure being USD 4-152 for a 100-piece run.
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, and the Vermeil Upgrade quote for it sits at USD 4-152.
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, shipped as retail box with care card and certified GRA report.
In a 100-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, which is USD 4-152 on the Vermeil Upgrade schedule.
girdle damage
Stones packed loose in a bag chip each other in transit. Individually wrapped parcels cost more and arrive usable, which is how the Vermeil Upgrade account reads it at USD 4-152.
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, shipped as retail box with care card and certified GRA report.
Where USD 4-152 Per Piece Actually Goes
Cost at USD 4-152 leaves no room for assumption. The table shows which line compresses and which line only moves quality down.
| Cost line | Share | What moves it |
|---|---|---|
| Base metal or alloy for loose Lab Grown Diamond Stones, Calibrated by Shape | 30% | Alloy choice and casting yield |
| Stone or melee for loose Lab Grown Diamond Stones, Calibrated by Shape | 20% | Sieve range and lot batching |
| Setting and finishing labor for loose Lab Grown Diamond Stones, Calibrated by Shape | 19% | Jig design and bench minutes |
| Plating, polish and QC for loose Lab Grown Diamond Stones, Calibrated by Shape | 12% | Per-tray versus per-piece checks |
| Packaging for loose Lab Grown Diamond Stones, Calibrated by Shape | 19% | retail box with care card |
A factory that cannot state its bench minutes per piece has never costed its own line. Ask for minutes and for the reject rule, not for a discount, quoted at USD 4-152 per piece in retail box with care card.
What US buyers Check Before They Sign
At USD 4-152 per piece the four measurements below are worth more than the discount being negotiated. One of them costs nothing to write down.
| Spec point | Common trade output | HOLYCOME standard | Cost if missed |
|---|---|---|---|
| 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 |
| Stone colour consistency | Graded by eye under D65 | Colour matched to a retained master stone, per tray | Repeat colour complaint in the same SKU |
| Sizing drift across the run | Not measured | Go/no-go gauge on every size, drift held under 0.15 mm | Resize queue and reship cost |
Write these into the Vermeil Upgrade purchase order and the arrival check becomes arithmetic instead of recollection, certified GRA report and packed retail box with care card at 100 pieces.
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 100-piece Vermeil Upgrade 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 4-152 for a 100-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 4-152 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 retail box with care card format at 100 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, the figure being USD 4-152 for a 100-piece run.
Certification is GRA 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, shipped as retail box with care card and certified GRA report.
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 100-piece Vermeil Upgrade order at USD 4-152.
How the Second Order Becomes Cheaper
The answer for loose Lab Grown Diamond Stones, Calibrated by Shape depends on four variables, and three of them are under the buyer's control, on a 100-piece Vermeil Upgrade order at USD 4-152.
We run this check per tray rather than per carton because the defect that matters on loose Lab Grown Diamond Stones, Calibrated by Shape is the one that repeats. A single odd piece is noise; a pattern across one tray is a process problem and it will be in every tray made after it, the figure being USD 4-152 for a 100-piece run.
The report the buyer receives states the count per tray, the measured average and the outlier count for loose Lab Grown Diamond Stones, Calibrated by Shape. It is deliberately unglamorous, and it is the document that settles most disputes before they start, on a 100-piece Vermeil Upgrade order at USD 4-152.
The Reject Tray Policy That Decides a Partnership
In the American bridal market, this is the single most negotiated line on loose Lab Grown Diamond Stones, Calibrated by Shape and the least documented one, with GRA report and retail box with care card stated on the same sheet.
The buyers who get the most out of loose Lab Grown Diamond Stones, Calibrated by Shape treat the first order as a measurement, not as a purchase. They buy a small run, measure the four numbers that matter, and then commit, which the Vermeil Upgrade file records at USD 4-152 in retail box with care card.
We support it directly on loose Lab Grown Diamond Stones, Calibrated by Shape: a 50-piece test run per design, the same gauge standard as a bulk order, and the same retained tray. Small does not have to mean loose, which is how the Vermeil Upgrade account reads it at USD 4-152.
Freight, Duty and the Arrival Check
Export runs through Guangzhou or Shenzhen. Air lands in 5-8 days on the US west coast, 7-10 on the east, and sea takes roughly three times the transit, shipped as retail box with care card and certified GRA report, and at USD 4-152 for 100 pieces that is the number the buyer signs.
FOB is the default on loose Lab Grown Diamond Stones, Calibrated by Shape and DDP is the option. Buyers new to the American bridal market usually take DDP once, then switch after they see the breakdown, and at USD 4-152 for 100 pieces that is the number the buyer signs.
If sieve drift appears in the arrival check, the retained tray decides who owns it. Keep the GRA report batch sheet in the same folder as the packing list, and 100 pieces leaves Wuzhou in retail box with care card at USD 4-152.
How a Repeat Order Gets Built
Nothing in this sequence is unusual, and that is the point. Each step exists because skipping it produced a specific failure on a previous order, certified GRA report and packed retail box with care card at 100 pieces, and the Vermeil Upgrade quote for it sits at USD 4-152.
- Sign the drawing at 1:1 scale with a millimetre grid, not a phone render.
- Cut the model in wax or resin and photograph it on the gauge before metal is committed.
- Cast the first article, set the stones and finish it exactly as bulk will be finished.
- Send the first article for approval with the weight and the stone measurements stated.
- Run the balance of the order in 25-30 days, holding the approved article as the reference.
- Ship with the approved article photographed beside a production piece from the same tray.
Reorders inside this sequence run 12-15 days because the model, the gauge set and the signed spec stay in our system, the figure being USD 4-152 for a 100-piece run.
What This Means for a First Order
A first Vermeil Upgrade order of 50 pieces per design at USD 4-152 tests the line rather than the range. Three designs covers the shelf.
Ask for the retained tray and the GRA report batch sheet with the first shipment. Both are free and both decide the reorder, with GRA report and retail box with care card stated on the same sheet.
