CAD, prototyping, casting, setting, plating and private-label packing under one roof — with three levels of custom, priced and timed honestly.
Pick the level that matches your budget — most first collections only need level one.
"Custom" means three different things in this industry, at three different prices. Adapting a model we already own can start at 30 pieces and ship in a week. A new design from your sketch needs CAD, a printed prototype and a mould, so it starts at 100–200 pieces and takes longer. Most brands that think they need level three actually need level one for their first collection — the piece looks identical and the tooling bill is zero.
| Level | Starting point | MOQ | Sample time | Tooling | Best for |
|---|---|---|---|---|---|
| 1 · Adapt an existing model | Our library — change stone, plating, size, finish, logo | 30 pcs | 3–7 days | None | Fast range building, market testing |
| 2 · Modify a design | Our model, reworked: new setting, different stone shape, added detail | 50 pcs | 7–10 days | Small, sometimes waived | A signature look without a full new mould |
| 3 · New CAD from scratch | Your sketch, tech pack, photo or physical sample | 100–200 pcs | 10–15 days | USD 80–350, owned by you | Protected, exclusive lines |
Level 3 is the only route where the design is genuinely yours and cannot be sold to another buyer. If that matters for your brand, budget for it deliberately rather than discovering it after the first reorder.
Most delays in custom work are not factory delays — they are files that cannot be made. A render with no dimensions, a stone size measured in carats but not millimetres, a wall drawn at 0.4 mm: each of these comes back as a question, and each question costs a day.
A production-ready file answers five things without anyone having to ask. If yours does, sampling starts the day it arrives.
| What the file must state | Typical value | Why it matters |
|---|---|---|
| Overall dimensions in millimetres | e.g. 18.2 × 12.4 × 3.1 mm | Renders are scaled by eye; millimetres are not |
| Stone sizes and shapes | Round 6.5 mm centre, 12 × 1.2 mm pavé | Carat weights do not convert reliably across cuts |
| Minimum wall thickness | ≥0.8 mm cast silver, ≥0.6 mm for small pendants | Below this, porosity and bending appear in wear |
| Prong and bezel thickness | Prong tip ≥0.6 mm, bezel wall ≥0.7 mm | The two places a piece fails first |
| Clasp, hinge or finding type | e.g. lobster 12 mm, or concealed push clasp | Determines cost and lead time more than the design does |
| Ring size system and tolerance | US 5–9, ±0.15 mm | A size run must be built into the mould, not filed later |
| Finish | High polish, satin, sandblast, black rhodium | Finish changes the polishing sequence and the price |
Accepted formats: AI, PDF, STL, 3DM, STEP and DXF, plus photographs with dimensions marked. If you only have a picture, send it with a ruler in frame and a stated diameter — we will build the CAD from that.
Three commitments, in writing, because they are the ones that get broken in this industry:
Ask any supplier for these three in writing before you send a sketch. A factory that hesitates on the first one is telling you something about the second.
3,800㎡ factory, 264 workers, 300,000+ pcs monthly capacity. See the full OEM & ODM capability list, or send a sketch with a target price and we will tell you which level it needs.
100 pieces for a new design in silver or brass, 200 where the piece is gold or has more than one moulded component. Simpler adaptations of existing models start at 30–50 pieces and need no tooling.
CAD 3–5 working days, sample 7–12 days after approval, bulk 25–35 days, plus shipping. A full custom piece is therefore 6–8 weeks door to door; an adaptation of an existing model is 4–5 weeks.
You do, when you pay for the mould. It is stored free for 24 months, used only for your orders, and never entered into our catalogue. We sign an NDA before CAD work starts if required.
Yes. We measure the sample or scale the photo with a stated dimension, then build the CAD. Reverse-engineering from a photo alone is unreliable for stone sizes, so we will ask for one measured dimension.
Yes: laser-marked or stamped logo on the piece, printed hang tags, pouches, boxes and barcodes, plus product photography for your listing. Print minimums sit with the printer — usually 100–500 per size.
Two revision rounds are included before the mould is cut, and one physical sample revision after. If the piece still does not match the approved render, we remake it at our cost — that is the point of approving a render with dimensions rather than a mood board.
Tell us the style, target price and quantity. Within 24 hours you will have material options, MOQ, plating spec and a production date — no obligation, no design fee.
