8,000 m² in Wuzhou: CAD, casting, setting, polishing, plating and QC in the same building.
The workshop is one building with the work arranged in the order the piece moves through it. That is deliberate: every time a ring leaves the building it gains a week and loses a pair of eyes.
Approved CAD files are printed in resin, then cast from a rubber mould for repeat orders or directly from the print for one-offs. A model is checked against the stone before anything is cast: seat depth, girdle clearance, the height of the gallery above the finger.
Silver and gold are cast in-house. The tree is invested, burned out and cast, then quenched and cut free. Castings are inspected for porosity before they reach a setter — a porous shank will fail at the size it is resized to, not at the size it was made.
Setters work under a microscope for pavé and channel work. Each stone is seated, checked for height against its neighbours, and tightened by hand. Tennis lines and eternity bands are set in a jig so the stones sit at a consistent height rather than one at a time.
Polishing is done in stages, with ultrasonic cleaning between them. Rhodium plating is applied to white pieces; gold-plated silver gets a thicker layer than the market norm because a thin plate wears through at the shank within months.
Every finished piece is checked for stone security, surface finish, size and weight. Stones are verified against the certificate before boxing. Anything that fails goes back to the bench, not into the outbound bin.






The factory films are shot on the floor, not in a studio: casting, setting and the interview our general manager gave to Guangxi TV.
Buyers are welcome by appointment at the Wuzhou showroom. If you cannot travel, send the brief and ask for a video of your piece being set — we film custom orders for clients who want to see the bench.
