We buy stones worth keeping.

Natural coloured stones of documented origin, with or without a report. Tell us what you have, as fully as you can, and one of us replies within a working day.

The house buys the stone before there is a design, and only stones it would be glad to keep. Sapphire, ruby, emerald, spinel, padparadscha, Paraíba tourmaline, alexandrite: natural, and ideally reported. What you do not know, leave blank. What you do, tell us in your own words.

City and country.

Asking price (optional)

A figure or a range, in any currency. Leave it if you would rather hear an offer.

How would you like us to be in touch? (optional)

Anything else (optional)

We use what you send only to consider the stone and reply to you. Nothing is shared, and nothing is kept if you ask us not to.

We read it

Everything you send is read by one of us, not sorted by a machine. If a detail is missing we ask for it before anything else.

We reply within a working day

With questions, or with an invitation to show us the stone in person or by video, under daylight lamps and the loupe.

We make an offer, or we do not

A stone we would be glad to keep gets a written offer. A stone that is not for us is returned with our thanks, and we say why.
