Third-Party Authentication of Designer Jewelry Pieces
JAGi Lab's GIA graduates & jewelry industry veterans can apply their knowledge of jewelry craftsmanship, brand history, and current designer jewelry market to authenticate your designer or brand-name jewelry pieces.
Our Designer Authentication service is an add-on to our CardCert Jewelry Appraisal service. We'll research the piece and confirm authenticity on the CardCert, providing an appropriate (if not current) retail value of the item.
Our lab does not authenticate Van Cleef & Arpels, Tiffany & Co., or Cartier jewelry pieces without a certificate of authenticity and receipt from original purchase.
