The workshop

The bench is upstairs from the shop

We are not a storefront placing orders elsewhere. Four stages, one setter, and a hallmark at the end of it.

01

The stone comes first

We source against your brief — cut, weight, colour, clarity, budget — and put certified options in front of you before a setting is drawn.

GIA · IGI certified

02

The setting is cut to it

Every stone is measured and the setting is made to those figures. Nothing is dropped into a stock mount and called bespoke.

CAD · wax · casting

03

Set by hand at the bench

Claws are raised, pavé is cut and beaded, and the piece is finished by the same setter from start to finish.

One setter per piece

04

Hallmarked before it leaves

All precious metal is sent to the London Assay Office and struck with our sponsor's mark, the fineness, the office and the date letter.
