How to Read a Jewelry Manufacturer’s Quotation: What the Line Items Mean
Two workshops quote the same drawing and the totals differ by thirty percent. Neither is lying. They are quoting different builds — and the gap sits in five lines you can point at, if the quotation has them. Read a quote as a build sequence and the number stops being a mystery.
A quotation is a build sequence with a price attached
Before a gram of metal is committed, someone has to read the drawing, decide how the piece is made, and notice what will not survive the bench. That work has a cost, and so does every operation after it: the model, the metal, the stones, the seat cutting, the polishing, the check at the end. A quotation is simply those decisions priced.
This is why two honest quotes can be far apart. One prices a sequence that includes a manufacturability review and a post-finishing check; the other prices a shape and hopes the rest works out. The number is the same kind of object in both cases. What sits behind it is not.
The five lines, and what each one should say
You do not need a cost breakdown to the cent. You need each line to state the thing that will be argued about later. This is the difference between a quote you can compare and a quote you can only feel good about.
Design and preparation: the line that predicts the rest
This covers everything before metal exists — reading the drawing for manufacturability, building the CAD model, printing a prototype, and marking up what will not survive production. It is the cheapest line in the quote and the one that decides whether the other four are accurate.
Look for evidence that the review actually happened: a returned drawing with comments, a note about a wall or a seat that has to change, a question about how the piece will be worn. A quote with no comment on the design is not a careful quote; it is a quote produced before anyone looked. The features that fail on the bench are exactly what this line exists to catch.
Metal: two numbers hide inside one
Metal is quoted by weight, and there are two weights in play: the metal poured or cut at the start, and the metal still present after filing, seat cutting and polishing. The difference is real and it is not small on a mirror-finished piece. A quote that says “18K” without saying which weight it means has left the most expensive ambiguity in the document.
The alloy choice moves this line more than most design decisions do: 18K is roughly three-quarters gold by weight, 14K a little over half, so the same volume of metal carries materially different gold cost. Platinum 950 is a different calculation again — denser, and worked in its own way on the bench. The alloy comparison is worth settling before you compare any totals.
Then ask for the tolerance band. A weight target with no band is not a specification; it is a wish. An honest band is stated as a range on the quotation, with the measurement basis next to it — weighed before or after setting, before or after final polish. Where the grams actually go explains why the basis changes the number more than the tolerance does.
Stones: grade language is where quotes quietly diverge
Stones are quoted per piece, per size, per grade — and the grade language is where two quotes stop describing the same thing. “White” is not a specification. “Good quality” is not a specification. Neither is a price per carat with no band attached.
What matters commercially is not the single stone but the set. A pavé row is read as a line, and a line is made by matching: size within the row, colour and clarity within a band, and enough stones from the same lot to finish the run. If the sample was set from one lot and the run from another, every stone can be in spec and the row still reads differently. On the pavé bangle in our cases, matching was settled before the first seat was cut — because after the seats exist, the row is no longer adjustable.
Bench and finishing: the least standardised line
This is where handwork lives — seat cutting, raising, joining, dressing back seams, and the finishing sequence itself. It is also the line most easily compressed without changing the drawing, which is why it is the first place to look when a quote is materially cheaper than its neighbours.
Compression looks like fewer finishing passes, a machine polish on a surface that needed hand work, or a finish specified only on the faces that photograph. Ask what the finish level actually is and who performs the last polish. On a piece with openwork or a pierced gallery, the answer matters twice over: the durability of the pierce depends on how the edges were dressed, not only on how they were modelled.
Inspection: small line, large absence
A quote that ends at “production complete” has not priced the moment that decides everything: the check of the finished piece against the approved reference. Ask what is checked, at which stage, against what, and what happens to a piece that fails — reworked, replaced, or counted anyway.
Stone retention deserves its own answer here, because it is the failure that reaches your customer rather than your inspector. The check that catches it has to happen after finishing, not before: the sequence is the whole point.
Three assumptions every number rests on
Every quote is a snapshot of a set of assumptions, and the cheapest quote usually rests on the most generous ones. These three decide whether the number survives contact with production.
How to compare two quotes in ten minutes
Put both documents side by side and work down this list. The goal is not to find the lower number; it is to find out whether the two numbers describe the same object.
- Match the metal basis first. Same alloy, same weight basis, same tolerance band. If any of the three differs, stop comparing totals.
- Match the stone specification. Size band, colour and clarity band, matching rule, lot reservation. “Same stones” is not a match — write the bands down.
- Count the operations. A quote with an operation list can be compared line by line. A quote with one lump sum can only be compared on faith.
- Look for the review and the check. Is there a design review line, and is there an inspection line? Their absence is not a saving; it is a transfer of cost to you.
- Ask what changes the number. A supplier who can name the three inputs that would move the price has priced the piece. One who cannot has priced the drawing.
What we put in writing
Our quotation states what the price assumes: alloy and karat, wall thickness where it matters, the operations in the routing, the stone specification, and the gates the run passes through. If one of those inputs changes, we say which line moves and why — before the work that the change triggers, not in the final invoice.
It also means we will sometimes be the higher number, and we will tell you what the difference buys. Occasionally the honest answer is that your design has a cheaper route — hollow construction, a different fabrication route, or a stone size that stops forcing the wall thinner. A quote with its assumptions written down is the only kind either side can defend later.
Questions worth sending back
These four come up in almost every first quotation, and the answer tells you more than the price does.
Why is the cheapest quote often the most expensive?
Because the number is not the cost. A quote that omits the design review, the finishing passes or the post-finishing check has moved that work to a later date and a different payer — usually you, at the point where the pieces are already made and the season is already running. The five places a low quote finds its margin are worth reading before you negotiate.
Is a per-gram metal price enough to compare?
No. A per-gram price without a weight basis and a tolerance band compares a rate, not a piece. Two suppliers can quote the same rate and deliver different weights, because one priced the model and the other priced the finished piece.
Should I insist on a full cost breakdown?
Insist on the parts that will be argued about: metal basis, stone specification, operation list, inspection gates. A supplier does not have to show their margin, but they do have to show what the price assumes. If they will not put those four things in writing, the number is not comparable — however detailed the rest of the document looks.
What if my design is not final yet?
Then ask for a quote with the open points named, and a note on which way the price moves when each one closes. That is more useful than a single number that quietly assumes the cheapest version of every open question.
What this means for your project
Send the drawing with the specification attached: karat, stone band, finish level, and the quantities you expect over the next twelve months. The reply will show you how the supplier thinks — a marked-up drawing and a sequenced quote is a build plan; a single number is a price-list entry.
