On the factory floor
Every photo below was taken in our own workshops. No stock images.




From drawing to shipping, all 9 steps in-house
Each step has its own workshop and its own craftspeople.

3D CAD
We model your photo, sketch or reference design in 3D and confirm the face size, thickness and ring sizes.

Model and mould
A wax model is printed and a rubber mould made from it. Every ring comes from this mould. New design samples from US$100, mould included; the cost is credited to your bulk order.
Lost-wax casting
Wax injection, wax trees, then vacuum pressure casting in 316L stainless steel to make the blanks.

Finishing
Sprues cut, pits filled and shapes trued, until each blank matches the model.

Stone setting
Micro pavé, prong, bezel or glued settings in zircon, crystal, pearl or resin.

Three-stage polishing
Rough, fine and buff mirror polishing, or brushed, sandblasted and hammered finishes.

Laser engraving
Fibre-laser logos, inside engraving, size and 316L stamps, at adjustable depth.

Plating
Gold, rose gold, black and natural steel. In-house plating workshop since 2018.

QC and packing
Every piece is checked against the approved sample for size, weight, plating colour and stones, then packed to your spec.

Factory advice for your first order
On a budget, start with the common sizes
US women’s 5, 6, 7 and men’s 7, 8, 9 cover most customers. Split the 100 pcs per colour across these sizes.
Start with few SKUs
Designs times sizes adds up fast in stock and cash. Test the market with a few designs, then add colours and sizes to the ones that sell.
Rings wear faster than necklaces
Rings rub against hands and desks all day, so thicker plating is worth paying for. Specify the thickness in your inquiry.
