Backed up by more than 75 years of experience and knowhow, all Tresor Jewellery is manufactured in our own factory in Belgium. By keeping the production local and in own hands from start to finish, Tresor chooses to differentiate itself from imported jewellery. Practically all items can be supplied immediately from stock and the collection is supported by an impeccable service. New and contemporary designs are added to the collection on a regular basis.
