SECURITY SEAL IGI was the first gemological laboratory to seal diamonds for security and protection purposes and continues to offer this standout service. As part of the sealing process a summary of your diamond’s IGI report is enclosed, visible from the back. Once opened, a chemically generated pattern is released, decisively showing the seal has been broken.
