Unfortunately, because of the vast number of designers in the field and constantly changing trends, we cannot authenticate all handbags. Our experts are able to authenticate most of the major brands of handbags, which are listed below. We are continually broadening the services we offer, so please check back regularly for an updated list. If the purchase of a particular designer of luxury handbags interests you, please contact us at support@colinsworth.com, and we’ll do our best to locate an expert to make that service available to you.
