What the Quote Actually Covers
A US independent jewelers and Shopify sellers sent us a competitor's buying Guide in October with one question: why does this fail at prong geometry after a season. We measured it, rebuilt the spec around stone retention after a 40-cycle wear test and prong tip height within +/-0.10 mm, and shipped 480 buying Guides that cleared inspection with zero rejects.
That rejection was avoidable at the drawing stage. prong geometry belongs on the spec sheet next to the stone size, not in the claim email three weeks after arrival. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
Our rebuild kept the buyer's retail price and changed four numbers on the bench. The next run cleared inspection because the specification traveled with the tray, not with a phone call. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
What American buyers Check Before They Sign
Most quotes describe the buying Guide and skip the part that determines the buyer's margin. Those four lines are listed below with the trade default beside our standard. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
| Spec point | Common trade output | HOLYCOME standard | Cost if missed |
|---|---|---|---|
| Prong Geometry on buying Guides | Inspected visually at the tray | Gauntlet check on every piece, limit written in the spec | Returns inside 60 days of wear |
| Rhodium Burn Off on buying Guides | Batch dependent, not logged | Thickness and tension logged per lot | Complaint after the second season |
| Size Step Drift on buying Guides | Estimated from nominal | Gauged per size with go/no-go tools | Resize queue and reship cost |
| Tolerance stack-up on buying Guides | Quote states nominal only | Worst-case band published per SKU | Freight and duty drift |
Write these four into the purchase order and the argument after delivery becomes arithmetic rather than recollection. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
Where USD 38-210 Per Piece Actually Goes
Buyers assume the stone dominates the cost of a buying Guide. At wholesale it is closer to a quarter, and the labor line is where two quotes for the same drawing diverge by double digits. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
| Cost line | Share | What moves it |
|---|---|---|
| Base metal or alloy for buying Guides | 32% | Alloy choice and casting yield |
| Stone or melee for buying Guides | 23% | Sieve range and lot batching |
| Setting and finishing labor for buying Guides | 21% | Jig design and bench minutes |
| Plating, polish and QC for buying Guides | 14% | Per-tray versus per-piece checks |
| Packaging and freight for buying Guides | 10% | Box grade and DDP versus FOB |
The cheapest quote for buying Guides usually hides its saving in the plating line and the stone grade. Both show up in the second season, not the first. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
The Three Failures We See Most in Incoming Samples
prong geometry
A prong that grips the girdle instead of the pavilion survives the showroom and fails the third ultrasonic clean. The seat has to be cut to the pavilion angle before the prongs close.
The commercial effect is a return shipment plus a resize labor claim, typically USD 9-14 per piece. Buyers who have seen it once put it in the purchase order; buyers who have not usually discover it on the first return.
rhodium burn-off
A 0.05 micron rhodium layer reads white in the tray and shows yellow at the shank in six months of daily wear. Thickness, not bath chemistry, is the variable that matters.
Our countermeasure is a gauge and a written limit. It adds about 22 seconds per piece and removes the defect from the run rather than from the carton.
size-step drift
A run gauged at size 6 and estimated elsewhere ships a size 8 that measures 7.75. The mismatch shows up as a resize queue two weeks after launch.
In a 480-piece run this typically shows on 8 of pieces. Catching it means measuring stone retention after a 40-cycle wear test at the tray level, not inspecting the finished carton.
What the Quote Actually Covers
Nobody quotes it for buying Guides until something goes wrong, which is exactly why it belongs in the first email.
At 480 pieces the arithmetic on rings 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.
We quote both a first-run price and a reorder price for buying Guides on the same sheet so the buyer can see where the curve flattens. Most flatten by the third run.
How a Repeat Order Gets Built
The calendar below is what we quote on a 480-piece run of buying Guides. It starts when the spec is signed, not when the deposit clears. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
- Spec sheet signed before casting: lost-wax cast, tolerances, plating thickness and packing format.
- Sample in 3-5 working days from stock components, or about 20 days if a new model is required.
- Production photos at three checkpoints: raw cast, post-polish, post-set, with buyer approval at each.
- Bulk in 15-20 days under 500 pieces; custom tooling runs 25-30 days.
- Pre-shipment QC report with per-tray counts and a retained reference tray for disputes.
MOQ is 50 pieces per design, low enough to test a category and high enough to keep the casting line accountable. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
AQL, Tray Checks and What a QC Report Should Say
The number is less interesting than the rule behind it, and buying Guides is where that rule gets tested.
One practical note on timing for rings: 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.
We date the buying Guides proforma from signature for that reason, and we state the deposit deadline in the same email that carries the spec sheet.
Alloy, Karat and the Cost of a Color Change
Buyers in North American retail tend to over-index on unit price for buying Guides and under-index on what happens after delivery.
There is a version of this that looks cheaper on paper and costs more in practice: quoting the best case on rings and letting the buyer discover the spread. It works once. The second order goes to whichever supplier quoted honestly.
We would rather lose a first order of rings on price than explain a defect after it lands. That position is unusual in this category and it is the reason our reorder share is high.
MOQ, Mixed Designs and the Real First Order
Most buying Guides disputes we arbitrate trace back to this line, not to the defect itself.
Buyers who get this wrong on rings usually get it wrong in the first order and correct it in the second. The cost of that correction is rarely the money; it is the four to six weeks of shelf time lost while a replacement run of rings is scheduled behind other orders.
Our approach is to write the rule into the buying Guides spec sheet before casting, then test it on the first tray. A rule that only exists in an email is not a rule, and a rule that is not tested is a hope.
What This Means for a First Order
The point of a small first run is not the margin. It is finding out whether the supplier's paperwork survives contact with the actual goods. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
The first order is the cheapest inspection a buyer will ever run, because the volume is small enough to check every tray by hand. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
Freight, Duty and the Arrival Check
Sea freight costs roughly a third of air and takes three times the transit, which only makes sense for an SKU already selling in North American retail. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
FOB is the default and DDP is the option. Buyers new to North American retail usually take DDP once and then switch after they see the breakdown. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
The arrival check is three steps: count cartons against the packing list, weigh a sample tray, and measure ten pieces against stone retention after a 40-cycle wear test and prong tip height within +/-0.10 mm. For buying Guides in this band the rule is the same on every tray of the run, not only on the first.
Frequently Asked Questions
What is the minimum order for buying Guides?
50 pieces per buying Guide. 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 we cannot keep the gauge check independent of the shift, which is the part buyers actually pay for on buying Guides.
How long does a reorder of the same buying Guide take?
12-15 days for buying Guides, because the model, the gauge set and the signed spec stay in our system. A first run is longer: 3-5 days for a stock-component sample, about 20 days if a new model is needed, then 15-20 days for bulk under 500 pieces.
Do you supply certificates for buying Guides?
IGI or GRA above 0.50 ct for buying Guides. Below that threshold we supply a batch report plus per-piece measurement of stone retention after a 40-cycle wear test, which is what most resellers need at the counter.
What finish do you use on buying Guides, and how thick is it?
Rhodium at 0.20 micron minimum on white buying Guides, with a palladium strike layer so wear-through reads white rather than yellow. Thickness is logged per lot and appears on the QC sheet, not only in the brochure.
How do you handle a rejected tray of buying Guides?
We replace or credit inside the same order cycle. The retained reference tray decides: if prong geometry shows on our retained buying Guide we own it, and if it appeared in transit we split the assay cost and file with the carrier. A typical exposure on buying Guides is a return shipment plus a resize labor claim, typically USD 9-14 per piece.
