How long it actually takes.

"A lead time of 25 days" answers a narrower question than buyers think. It describes how long the factory floor takes once everything is approved and materials are in. Your project starts earlier and ends later than that.

Here is the whole sequence with honest timings, and the two places where a schedule usually slips.

The short answer

Add those up and a first project with one revision round lands somewhere around six to nine weeks door to door. A settled design with no revision and standard packaging can move in 15–20 days from confirmed design to shipment — that is the fastest realistic window, not a standard one.

Why sampling takes 7–10 days

Not because the piece is difficult to make. Because a sample passes through several independent steps, and each one has its own queue:

• Engineering review. The drawing or reference is checked for wall thickness, undercuts, draft angle and how the piece will actually be held for polishing. A design that looks fine as a sketch can be unmanufacturable at 2 mm.
• Tooling or CNC. A simple flat piece may go straight to laser cutting. A cast piece needs a mould, and mould cutting is the long pole.
• Forming or casting. One day for most pieces.
• Polishing. This is where stainless steel is slow. Every piece is hand or barrel polished, and polish quality cannot be rushed without it showing.
• PVD coating. A vacuum chamber run, and your sample usually waits for a chamber cycle rather than dictating one.
• Engraving, if specified. Laser engraving is fast; deep engraving or enamel filling is not.

A 7-day sample means everything went smoothly. A 10-day sample means one step had a queue in front of it. Neither indicates a problem.

Why bulk production takes 20–35 days

The 15-day band between the fast and slow ends is almost entirely about volume and colour count, not about the design being hard.

Volume. A 300-piece run and a 3,000-piece run pass through the same steps but spend very different amounts of time in each. Polishing and inspection scale close to linearly with piece count.

Colour count. Each colour is a separate PVD chamber cycle. Four colours is four runs, and a piece cannot shortcut the queue because it is small.

Component matching. A necklace is a chain, a pendant, a clasp and a tag, and all four have to arrive before assembly. If one component runs late, the whole order waits — this is the single most common cause of a run landing at 35 days instead of 22.

Congestion. Factories run multiple clients. A run quoted at 25 days in a quiet month is still 25 days in a busy one, but the buffer disappears.

The two places schedules actually slip

Neither of them is the factory floor.

Round trips on the sample. Every revision round costs 5–7 days, and most first projects take two rounds. A brand that approves the sample in one review saves a full week; a brand that circulates it internally for ten days, then asks for three unrelated changes, adds three weeks to a project that the factory quoted at 25 days.

Artwork and packaging approval. Logo files, packaging print proofs, colour references, barcode placement — these approvals run in parallel with production in theory and sequentially in practice, because nobody chases them until the goods are ready. Packaging minimums often exceed jewelry minimums, so a late packaging decision can hold finished goods in the warehouse.

How to compress a timeline honestly

Five things that genuinely work:

1. Send a physical reference or a dimensioned drawing, not a mood board. Engineering review starts immediately instead of after a clarification exchange.
2. Decide the colour count before sampling. Adding a second colour after approval restarts a chamber cycle.
3. Approve packaging artwork while the sample is in production. The two tracks are independent; run them together.
4. Consolidate approvals into one round. Collect every comment internally, then send one list. Three separate emails of small changes cost three rounds.
5. Choose a lower-tooling construction for the first run. Laser-cut flat pieces skip mould cutting entirely.

What we will not do

We will not quote a lead time that assumes your approvals arrive same-day. If a project's real schedule depends on a decision you have not made yet, the honest answer is a range with the dependency named — which is what the table above is for.

If you have a hard launch date, tell us the date at the brief stage rather than at the end. It changes what construction and what quantity we would recommend, and it is much easier to protect a date from the beginning than to rescue it later.
