Cartier, Van Cleef & Arpels, Boucheron, Bulgari, Chaumet: a signature is verified, dated and valued at 22 rue Drouot — then bought directly, with immediate payment.
A signature is not a price; it is a starting point. We read the engraving, the serial number and the maker's mark, date the mounting, examine the stones and value the piece against the international market for that house and that period. Then, if you wish, a firm offer is made on the spot. For loose stones, see precious stones; for an inherited collection, estate jewellery.
Verifiable facts, reviewed in September 2026.
Engraving, serial number, maker's mark, consistency of the mounting with the period. Depending on the house, a certificate of authenticity may be requested from the original workshop — paid, several weeks.
They count in the price; their absence prevents neither the expertise nor the sale. Do not have a signed piece polished or repaired before the opinion: original condition is what is paid for.
We also buy fine unsigned French jewellery from Parisian workshops. The eye decides, not the label.
