A bridal buyer in Manchester scheduled a campaign launch for mid-November and placed a 400-piece moissanite ring order on September 20, giving herself eight weeks. The factory promised 35 days. It shipped on November 22. Two weeks of delay came not from broken equipment or missing gold, but from the predictable parts: sample approval round two, plating queue, and a customs documentation recheck. Lead time is almost never a single number. It is the sum of six queues, and queue time usually dwarfs bench work. Here is how we book ours, and where your order is most likely to slip.
The real department-by-department timeline
A standard 925 silver or 14k gold wholesale order, after sample approval, moves like this:
| Stage | Bench work | Queue / wait | Notes |
|---|---|---|---|
| CAD & wax print | 1-2 days | 1-2 days | First-time styles need a wax approval |
| Investment casting | 1 day | 1-2 days | Trees are grouped by metal |
| Stone setting | 2-3 days | 2-4 days | Pavé runs slower than prong |
| Polishing | 1-2 days | 2-3 days | High-polish vs matte has different queues |
| Plating & rhodium | 1 day | 2-5 days | Chemical line runs in batches |
| QC & packing | 1 day | 1-2 days | Certificate matching adds half a day |
Add it up and a straightforward 200-piece order takes 18-28 working days after sample approval. Add a sample round, and you add 7-10 days at the front. Add a metal change or a new stone size, and you add another 3-5 days.
Where orders actually slip
Our internal post-mortem on delayed orders over the last twelve months points at four causes, in order:
- Sample approval loops (41% of delays): The buyer asked for a tweak after the sample was approved, which means the wax tree gets re-cut. Each approval round is 5-7 days.
- Material availability (22%): 14k gold and specialty moissanite sizes have to be ordered in. We hold 925 silver and standard round moissanite in stock.
- Plating queue (19%): Rhodium and 18k gold flash plating run on a chemical bath schedule; small jobs wait for a full bath.
- QC rework (18%): A prong that fails pull test means the piece returns to the setting bench, which resets the queue.
None of these are crises. They are scheduling facts. The buyer who plans around them gets their stock on time; the buyer who treats 35 days as a guarantee does not.
How to compress lead time without paying a rush surcharge
You cannot speed up the bench. You can remove the queues.
- Approve the wax, not the final piece. Wax approval is a 3-day step. Final sample approval after casting is 10 days because it includes setting and polish.
- Use stock tooling for the opening run. If a factory already cast the style last season, you skip CAD and wax entirely. That saves 5-7 days.
- Lock metal and stone specs in the PO. A change to 14k rose gold after PO sign-off triggers material ordering. Put it in writing.
- Bundle plating. If your order includes rhodium silver and gold-flash pieces, ask to plate them in one bath run instead of splitting.
What the timeline looks like for different buyers
First-time boutique opening an order: Budget 35-45 working days end to end: 10 days for CAD and wax approval, 20-25 days for production, 5-7 days for QC, packing, and DDP shipping to a US or EU port.
Reorder buyer on proven tooling: 18-25 working days. No sample round, no new wax. The order goes straight to casting queue.
Private label chain with rolling forecast: We pre-cast the components in one large tree and hold finished settings. Pull-to-order shipments go out in 5-7 working days.
Frequently Asked Questions
What is the standard lead time for a 200-piece wholesale order?
After sample approval, 200 pieces of sterling silver or 14k gold jewelry typically ship in 18-28 working days. Add 7-10 days if a first-time wax approval is required, and 5-7 days for DDP ocean or express air freight to the US or EU.
Does moissanite take longer than CZ?
Slightly. Standard round moissanite we hold in stock, so it does not. Specialty cuts (oval, pear, emerald) and sizes above 7mm are ordered in and add 3-5 days to the material lead time.
Can I rush an order in 10 days?
Sometimes, on existing tooling and stock material. Rush surcharges run 25-40% on the labor line because the order jumps every queue. It is cheaper to plan two weeks ahead than to rush.
Why does my sample take longer than the production run?
Because a sample goes through every department as a one-off job, waiting behind real production. A 20-piece sample can take as long as a 300-piece run, even though it uses 7% of the material.
How does shipping affect total lead time?
DDP air freight to the US or EU adds 5-7 days. DDP ocean freight adds 25-35 days but cuts per-unit shipping cost by roughly 70% on orders over 50kg. Budget accordingly.
Key takeaways
- Lead time is six queues, not one promise. Ask the factory for a department-by-department schedule, not a single number.
- Sample approval loops cause 40% of delays. Approve the wax early and lock specs in the PO.
- Reorders on existing tooling ship in half the time of first orders. That is the real reason to reorder the hero SKU.
- Plan DDP shipping into the date. Ocean is cheap but slow; air is fast but eats margin on low-ticket pieces.
