A US retailer ordered 3,000 moissanite solitaire rings in March for a July promo. The supplier said "yes, no problem" on day one. By June 12 only 1,100 rings had shipped. The factory had quoted ambition, not capacity. For wholesale buyers, understanding real production capacity — not the marketing slide — is the difference between a stocked Q4 and an empty storefront. This article breaks down how a jewelry factory actually counts its monthly output and how you should plan against it.
The capacity numbers buyers should demand
When a sales rep says "we do 50,000 pieces a month," that figure is almost always the theoretical maximum across every bench and every product type. Your order is one product type, with one setting style, in one metal. Real usable capacity for your SKU is a fraction of that headline number.
We publish our rolling 90-day capacity by zone so buyers can see what is actually open.
| Production zone | Theoretical / day | Realistic / day (our floor) | Typical small shop |
|---|---|---|---|
| Casting (trees) | 1,200 pcs | 850 pcs | 300 pcs |
| Stone setting | 600 pcs | 420 pcs | 150 pcs |
| Polishing | 900 pcs | 650 pcs | 250 pcs |
| Plating + QC + pack | 1,000 pcs | 700 pcs | 300 pcs |
The bottleneck zone sets your lead time. For pavé work that is almost always setting; for plain bands it is casting. Ask your supplier which zone is the constraint on your order, not what the total factory output is.
How capacity actually gets booked
Factory capacity is not a free queue. It is allocated by PO date, by customer tier, and by material. A few rules you should know:
- Material holds 5–10 days. Sterling silver grain and 14k gold do not sit on the bench waiting. Once your PO is confirmed, alloy sourcing is the first critical path.
- Cast weeks are booked in waves. Most factories run casting twice a week. Miss the Tuesday tree and your whole order slips by three days.
- Setters are per-skill. A setter who does great pavé is slow on channel setting. Do not assume the whole bench flexes to your SKU.
- QC and packing are the hidden bottleneck. At peak season, finished stock piles up at inspection. Plan 5 extra days here in November and December.
Our published capacity vs industry habit
Most shops quote lead times from the moment your deposit clears. We quote from material-in-house, because that is the only date that cannot slip. Our standard production window for 500 pieces is 25–30 working days; the industry commonly quotes 18–22 and then runs to 35. The honest number is longer but predictable.
For repeat orders on existing tools, we hold a 10% capacity slot for our private-label customers every month. That means a reorder of 200 pieces ships in 12–15 days instead of re-entering the full queue. This is the detail that protects your store's stock level between seasons.
Plan your order by buyer profile
Opening buyers (100–500 pcs): pick two or three SKUs, not ten. A focused order moves faster and lets you test which style sells before you commit capacity. Ask for a capacity-hold confirmation in writing before you pay the deposit.
Growing boutiques (500–2,000 pcs): split into two waves. Wave one for fast sellers, wave two held 30 days later. This avoids locking cash in 2,000 pieces of one style.
High-volume brands (5,000+ pcs): negotiate a standing capacity slot per quarter. Factories reserve bench time for committed customers at a slight unit discount, and you skip the queue every reorder.
Frequently Asked Questions
How long does a 500-piece jewelry order actually take?
Plan 25–30 working days from confirmed materials to shipping for 500 mixed pieces. Reorders on existing tools drop to 12–15 days because casting and CAD are already approved.
Why do factories always slip the lead time they quoted?
Most quotes start the clock at deposit, not at material arrival. Alloy sourcing, plating bath prep and QC backlog each add unplanned days. Ask for a date from material-in-house instead.
Can I rush a wholesale order?
Yes, but expect a 15–25% rush surcharge and only if the bottleneck zone (usually setting) has an open slot. Rush orders still skip nothing in QC.
How much capacity should a factory keep for reorders?
Serious wholesale partners reserve 10–15% of monthly bench time for repeat customers. If your supplier cannot commit a reorder slot, they are treating you as a one-off.
Does capacity change by metal?
Yes. Sterling silver casts faster and polishes quicker than 14k gold. Gold orders add roughly 5–7 days per 500 pieces because of slower casting cycles and stricter alloy checks.
Key takeaways
- Headline monthly output is meaningless; ask for the bottleneck zone on your SKU.
- Trust lead times measured from material-in-house, not from deposit.
- Reorders on existing tools should ship in 12–15 days with a held capacity slot.
- Split growing orders into waves to protect cash flow and stock turns.
