01 The collections

Start with a category

Every piece is made to order. Choose a stock design and change the metal, stone size, band width and finish — or send a drawing and we start from zero.

02 Inside the workshop

One factory, every step under our roof.

Design, CAD, casting, stone setting, polishing, plating and final QC all happen in the same building in Wuzhou — which is why we can hold a lead time instead of guessing at one.

  • CAD drawn to your finger size before anything is cast
  • Wax, cast and pre-polish in-house; no outside benches
  • Stone matching and setting done by our own setters
  • Three-stage QC: pre-polish, post-set, pre-dispatch
  • GRA / IGI certificates matched to each stone

A walk through the floor

From the bench row to the lapping wheels and the torch — the same floor that runs stock reorders and bespoke CAD work.
