A confidential sale in three steps

Payment

Accept the offer and receive same-day payment by bank transfer or cash, subject to identification.

What determines a piece's value

Every category has its own nuances — a signed Art Deco brooch is judged differently to a modern diamond ring — but six factors shape almost every valuation we make.

Designer & Maker

Signed pieces by recognised houses — Cartier, Van Cleef & Arpels, Boucheron — command a premium over unsigned equivalents.

Gemstone Quality

Carat, colour, clarity, and cut all matter — and for coloured stones, origin can significantly affect value.

Period & Rarity

Georgian, Art Deco, and Belle Époque pieces are often rarer and more sought after than later reproductions.

Condition & Alterations

Original, unaltered settings are prized by collectors. Remodelled or resized pieces can see reduced value.

Provenance & Signature

Original boxes, certificates, and maker's marks increase both value and buyer confidence in authenticity.

Hallmarks & Certification

Gold and platinum hallmarks, alongside gemmological certificates, support a stronger, more confident valuation.

Auction versus private sale

Selling through auction can mean a long wait and significant deductions before any proceeds reach you. Here’s how a private sale with us typically compares.

Selling your jewellery, clarified

Q. How do I get a valuation for my jewellery?

Send clear photographs of your piece — including any signature, hallmark, or certificate — via WhatsApp or our online enquiry form. Our specialists provide a free, no-obligation valuation, usually within hours.

Q. Do you buy jewellery without a certificate or original box?

Yes. While certificates, boxes, and papers can increase value, we regularly acquire pieces sold without them, provided authenticity can be confirmed.

Q. How quickly will I be paid?

Once a valuation is accepted, payment is made the same day, by bank transfer or cash, subject to identification checks.

Q. Is the valuation confidential?

Entirely. There is no public auction exposure. Appointments can be arranged privately at our offices, at your home, or at a partner hotel.
