One-man custom goldsmith studio

When it doesn't exist,I make it.

Bring me the photograph, the drawing, the old piece, the wrong size, or the idea nobody else could execute. One goldsmith handles the CAD, printing, casting, setting, finishing, and final polish.

Start with what you have

There is no standard way into custom.

Most people do not arrive with perfect specifications. They arrive with something they cannot buy. That is enough to begin.

01

I have a photograph

Use the feeling, proportion, and details as the start of an original custom build.

02

I have a drawing

Turn a sketch or rough concept into production-minded CAD and, when needed, finished metal.

03

I have an old piece

Evaluate what can stay, preserve what matters, and build a new direction around it.

04

I cannot find my size

Build for the right proportions instead of forcing the closest catalog option.

Yao is the goldsmith behind Cast House. Your questions go to the same bench making the decisions, and the work stays with one person from the first reference through the final polish.

You see the rough castings, setting work, problems being solved, and final reveal. The process is part of the proof.

Range without a house style

Heavy, delicate, sentimental, impossible.

The work changes because the piece changes. The standard is whether it was executed correctly.
