A stone can outlive three owners.

Bring in a piece that has already lived a life. We take the stone out of the setting it has outgrown and build it something new around the same measurements it has always had. The stone stays. Everything around it changes.

Most resets run four to six weeks

How a reset runs

01

Out of the old setting

The stone comes out at the bench, under the microscope, with the old setting kept whole wherever we can. If the mount has a story, you keep it.

02

Measured and drawn for

The stone is measured, papered and drawn for like any stone we buy, except this one arrives with its provenance already attached.

03

Set again and hallmarked

A new setting is built around the old dimensions, hallmarked, and handed back with both papers. Grandmother’s stone, your ring.

Tell us about the piece

Bring it in.

The first look costs nothing, and the stone never leaves your sight unless you want it to.
