Request a factory quote
The more specific your brief, the more useful our reply. If you already have a stone list, a reference photo or CAD files, mention it — we will tell you MOQ, lead time and tiered pricing in the first response rather than sending a catalogue and asking questions later.

What happens after you send this
- Within 12 working hours — a named merchandiser replies with pricing at your quantity tier, MOQ per design, lead time and shipping options.
- If the specification is open — we propose two or three stone and metal combinations that hit different retail price points, so you can choose on margin rather than guesswork.
- If you want to see quality first — we send a sample at list price. The sample cost is credited against your first order above 200 pieces.
- If you approve — we issue an approval sheet covering stone grade, tolerances, metal, plating, dimensions, packing and lead time. Production starts only after you sign it.
To get a precise quote in one round trip, include
- Product type and style reference (photo, sketch or existing SKU)
- Stone: moissanite, lab grown diamond or lab grown gemstone, plus shape and size in ct or mm
- Colour and clarity target, and how much tolerance you will accept
- Metal: 925 sterling silver, 10K, 14K or 18K gold, and colour
- Quantity per design, and whether you want a mixed first order
- Destination country and whether you need assay or material declarations
- Packaging and branding requirements
Wholesale account or single order?
Both are welcome. Most buyers start with a trial order of 50–100 pieces across several designs to test grading consistency and packing, then move to scheduled replenishment once they are confident. If you are planning a full season or a private-label launch, tell us the annual volume in your first message — a written forecast is what allows us to reserve production capacity and reduce your per-order minimum.

How your jewellery is actually made
These are photographs from our own bench in Wuzhou, in the order the work happens. Nothing here is outsourced: the same team selects the rough crystal, cuts and polishes the stones, casts, sets, polishes the metal and inspects the finished piece before it is packed.
The workshop
Test reports & registrations
Every material we ship is tested for nickel, lead and cadmium release by independent laboratories — SGS and CTT International — and we keep the reports on file. Ask us for the current report for a specific material or SKU and we will send it with your quotation.
Reports shown were issued to our manufacturing operation; document numbers and dates are legible on the originals and copies are available on request.
