Craftsmanship

Set by hand,
considered twice

Each piece begins as a drawing, then a wax, then a single casting. Stones are chosen individually, matched for colour and life, and set under the loupe. Galleries are pierced, edges softened, and the finish brought up by hand over several days — the work you cannot see is the work that lasts.

Nothing leaves the atelier until it has been reviewed twice.
