Book an appointment for an appraisal
To arrange an appraisal appointment, call us on 01 48 87 81 44, Monday to Friday, from 10am to 1pm and from 2pm to 6.30pm: we will agree together on a time that suits you. An appointment guarantees you a time slot with no waiting — useful if you are coming from far away, if you have several pieces to show or simply have little time.
You can also come without an appointment, during the same hours, to 43 rue Beaubourg (Paris 3rd, métro Rambuteau). The appraisal takes about twenty minutes; it is free and commits you to nothing.
Before travelling, you can send us a few photos on WhatsApp: we will tell you whether your piece matches what we are looking for.
