Lalique Gallery's owner Benjamin Janssens is an expert in pre-war Lalique and is one of the few specialized Lalique dealers in the Netherlands. Janssens conducts research, has several publications to his name and has an enormous international network, including the descendants of René Lalique himself. Lalique Gallery collaborates with major museums such as the Museo Calouste Gulbenkian in Lisbon, the Louvre Museum in Paris and the Metropolitan Museum of Art in New York.
The Lalique Gallery partly cooperates with the Dutch Lalique Museum and is located within the museum in a separate room. Part of the cooperation is the so-called 'loan agreement'. In this agreement, an object can be purchased from the Lalique Gallery for a purchase price, provided that the Lalique Museum is allowed to have the purchased object on loan once for a mutually agreed period of time.
