A sourcing manager is placing a capsule of thirty pieces and has to decide between two production routes. Route one is hand fabrication: a bench jeweller saws, solders and shapes each piece from sheet and wire. Route two is lost-wax casting: a wax model is made, a mould is taken, and pieces are cast in multiples. The two routes produce pieces that look similar on a photo but sit at very different price points, lead times and order minimums. Choosing the wrong one either prices the line out of the market or under-delivers on the handcrafted story the marketing promises. This overview explains the trade-offs in numbers so the decision is made before the PO, not after the first sample.
What each process costs and why
Handmade fabrication is labor-intensive. Each ring, pendant or earring is built by one jeweller from raw material, which means high unit cost but almost no upfront tooling. It suits one-off commissions, small batches of twenty to fifty pieces, and designs where the visible texture of handwork is part of the product. Casting amortises a wax model and rubber mould over dozens or hundreds of units; the per-piece labor drops sharply once the mould exists, but there is a tooling and model cost up front. That is why a cast design at 500 units can cost a third of the equivalent fabricated piece, while a single fabricated piece may cost less than the cast route once tooling is included. Our note on mine-to-retail pricing shows how these production costs flow into the price the store sees.
Tolerance, lead time and minimum order
Casting wins on consistency. Because every piece comes from the same mould, repeated units match to within a fraction of a millimeter, which matters when you are shipping 500 identical studs and customers compare pairs. Handmade pieces show slight variation, which buyers often want for an "artisan" line, but which can be a problem for matching earrings or stacked rings. Lead times follow the same pattern: a fabricated order of twenty pieces may ship in two to three weeks, while a cast order of 500 needs a wax, a mould and a casting run, typically four to six weeks before polish and plating. Minimum order quantities are the lever: MOQ and factory audit planning covers how to read a supplier's minimum, and our wholesale buyer tips walk through sampling before a large run.
When to choose which
Choose fabrication for small, story-driven runs where the hand finish is the selling point, for one-off design development, and for pieces that need structural work (heavy hinges, custom settings) that casting does not do well. Choose casting for production of repeatable designs above roughly fifty units, for paired earrings, and for complex shapes that would be impossible to solder by hand. Most production lines use both: cast the bulk, hand-finish the edges and settings. Whatever the route, the finished pieces must carry correct fineness marks; the ISO 9202 fineness standard and 16 CFR Part 23 marking rules apply to both, so confirm the stamp is applied after plating in the finishing stage, which is where plating thickness and wear also get decided.
Request a sample before scaling
Whichever route you choose, never place a full PO before approving a physical sample. Ask for one hand-fabricated unit and one cast unit of the same design side by side, and compare the finish, the weight, the interior comfort and the consistency of the stones. The sample tells you things a photo cannot: whether the solder joints are clean, how the plating wears on the sample you carried for two weeks, and whether the comfort fit actually feels right. Build the sample cost into your budget, because it is far cheaper than discovering a tolerance problem after 500 units are in stock. Most factories absorb the sample cost against a future order, so ask up front rather than assuming it is a sunk expense.
Frequently asked questions
Is handmade jewelry always better quality?
Not necessarily. Handmade offers unique texture and craftsmanship, but casting delivers tighter consistency between repeated units. "Better" depends on what the line is selling.
At what order size does casting become cheaper?
Roughly above fifty units the mould cost amortises and cast per-piece cost falls well below fabrication. Below that, handmade is often cheaper once tooling is removed.
Why do cast pieces cost less per unit?
Because the wax model and mould are reused across the whole run. Fabricated pieces are built individually every time, so labor scales with quantity.
Can a supplier mix both processes?
Yes, and most production lines do: cast the base piece, then hand-finish settings, edges and texture to blend consistency with craftsmanship.
HOLYCOME runs both fabrication and lost-wax casting under one roof, so you can sample small and scale to production without switching factories. Ask our team for a process recommendation and quote on your design.
