A 32-door accessory chain in Columbus asked for 500 stones at a landed price of $4.20 and the second order came back at $5.60 because the first quote excluded plating thickness and stone matching, and the buyer had already published a $9.99 retail price. The order was not lost on price. It was lost on a specification nobody wrote down. This piece looks at stones & materials from the buyer's side of the table: what the promise means at the bench, what it costs to get it wrong, and how to write a brief a factory can be held to.
Why the Quoted Unit Price Almost Never Survives the First Reorder
The number that kills a wholesale programme is not the unit price. It is the second unit price. A quote that assumes one plating lot, one stone parcel and one production run is a quote for one order, not for a year of reorders.
We publish the cost stack so a buyer can see which line moves. That is the only way to keep a retail price stable while metal and stone costs move underneath it.
What the Industry Standard Delivers, and Where It Breaks
The default offer in this category is a stock photo, a unit price and a thirty-day promise. That works for one order and stops working on the second, because a stock photo cannot specify calibrated rounds from 0.8mm to 12mm.
| Comparison | Common practice | What we hold | Why it matters |
|---|---|---|---|
| Cost line | Common quote | Our quote | |
| Base metal | spot + 8% | spot + fixed fabrication, locked quarterly | |
| Plating | not itemised | 0.05-0.10 micron rhodium, priced per piece | |
| Stone matching | flat allowance | parcel graded, priced on hue band | |
| Setting labour | hidden in unit price | per-operation, visible on the sheet |
How We Build a Price That Holds for Twelve Months
Parcel diameter and hue spread is the number we publish per lot. It is the one a buyer can check with a caliper and a loupe in ten minutes, and the one that decides whether a reorder is a formality or a negotiation.
- Lot and rack reference on every carton
- Calibrated rounds from 0.8mm to 12mm declared on the invoice, not assumed
- One plated sample approved per rack before the run
- Stone parcel photographed and hue band stated in writing
Tolerance Stack: Where 0.1mm Becomes a Complaint
Tolerance compounds across operations. A casting that runs 0.15mm wide, a setting that shifts the stone 0.1mm, and a polish that removes 0.05mm of surface can put a parcel of loose stones outside the size the customer ordered without any single step being out of specification.
That is why we hold the stack at the casting rather than at the finish. Tightening the last operation cannot recover tolerance that was already spent at the first.
The Reorder Sheet We Hand Back
Every reorder comes back with the original sheet: alloy batch, stone parcel reference, plating rack number, setting team, measured parcel diameter and hue spread. It is four lines and it removes the argument about what "the same" means.
Buyers who keep those four lines can audit a fifth lot in an afternoon. Buyers who do not are comparing two photographs and hoping.
Packaging and the First Thirty Seconds
The carton is the first physical impression. An anti-tarnish pouch, a cavity insert and a stone-side-up orientation cost a few cents and prevent most of the transit damage we see on loose stones.
Loose fill is the main cause of bent posts and scratched faces. It is cheaper than a cavity insert by about two cents a unit, which is the worst trade in the category.
Why We Publish the Numbers
Publishing parcel diameter and hue spread and the plating micron figure is uncomfortable for a factory that expects to be judged on photographs. It is comfortable for a buyer who has to defend a reorder to a boss.
The number is the argument. A supplier who will not publish one is asking you to trust the photograph instead.
The Three Failure Modes We See Most
On loose stones the three failures that come back most often are mixed hue inside one parcel, diameter drift of 0.3mm, and stones that will not seat in a calibrated setting. Each has a root cause upstream of the bench, which is why sorting finished pieces never fixes the rate.
Prong wear traces to wire gauge and setting pressure. Stone tilt traces to the bearing surface being cut by hand instead of by burr. Plating burn-off traces to rack contact points, not to the tank.
Tolerance Stack: Where 0.1mm Becomes a Complaint
Tolerance compounds across operations. A casting that runs 0.15mm wide, a setting that shifts the stone 0.1mm, and a polish that removes 0.05mm of surface can put a parcel of loose stones outside the size the customer ordered without any single step being out of specification.
That is why we hold the stack at the casting rather than at the finish. Tightening the last operation cannot recover tolerance that was already spent at the first.
What Changes Between Lot One and Lot Five
Repeatability depends on four inputs staying fixed: the alloy batch, the stone parcel, the plating tank and the setting team. Swap any one of them to save cost and the fifth lot looks like a different product to your customer.
We keep the lot record for all four, so a reorder is compared against your first lot rather than against a photograph on a website.
What We Will Not Do, and Why That Protects You
We will not quote from a stock photo, we will not promise a date the plating queue cannot hold, and we will not sell a design we made exclusively for one buyer to another buyer.
Each of those is a short-term sale and a long-term loss, and the loss lands on the buyer who trusted the quote. Saying no to them is the cheapest quality control we operate.
Why We Ask for the Tolerance Before the Drawing
A tolerance stated after the drawing is a complaint waiting to happen. State it before and it becomes a manufacturing instruction, which is a very different conversation at the bench.
Most disputes we see are not about quality. They are about two people who each thought the other had agreed to a number that nobody wrote down.

What It Costs and How Long It Takes
Fifty pieces per design is the working minimum on stones & materials. A sample runs three to five days, bulk fifteen to twenty days under 500 pieces, and a custom mould twenty-five to thirty days from drawing approval. Payment is 30% deposit with the balance against the bill of lading copy.
If the order is below fifty, the setup cost per piece roughly doubles because the casting tree and the plating rack are fixed costs. That is arithmetic, not a policy to negotiate around.
| Item | Value | Note |
|---|---|---|
| MOQ | 50 pcs / design | sizes and colours can be split |
| Sample | 3-5 days | one piece, approved before the run |
| Bulk lead time | 15-20 days | under 500 pieces |
| Custom lead time | 25-30 days | from drawing approval |
| Payment | 30% / 70% | balance against B/L copy |
| Port | Guangzhou / Shenzhen | export from Wuzhou |
Frequently Asked Questions
What is the minimum order for stones & materials?
Fifty pieces per design, and you can split that across three ring sizes or two plating colours without a surcharge. Below fifty, the setup cost per piece roughly doubles because the casting tree and the plating rack are fixed costs.
Do prices change between orders?
Metal moves, so we quote a base plus a metal adjustment clause reviewed quarterly. Your unit price stays flat inside the quarter, and the clause is one line you can audit against the London fix rather than a vague surcharge.
Can you match a competitor's price?
Usually we can show why their price is lower. It is normally thinner plating, a lower stone grade, or a stock photo instead of a production sample. We will quote the same specification and let you compare like for like.
What payment terms apply?
Thirty per cent deposit with the balance against the bill of lading copy. For repeat buyers past three clean orders we move to thirty days after shipment on approval.
Can you produce a second lot identical to the first?
Yes, if we hold the four inputs: alloy batch, stone parcel, plating tank and setting team. The reorder sheet records all four, so the check happens against a document rather than against a memory.
What happens if the lot arrives outside the agreed tolerance?
Photograph the piece with a scale and reference the lot line. Above the agreed AQL we replace and cover freight; inside it we replace the affected units inside ten days.
