Mislabeled diamond causes GIA to suspend sealing service

Rob Bates

Gemological Institute of America’s lab has begun an investigation and suspended its diamond sealing service after it spotted a sealed diamond the report of which didn’t match the stone.

Diamond sealing—which involves putting the gem in a secure tamper-resistant package — is an additional service offered by the lab, generally for the investment market. Only one-tenth of one percent of the stones that the lab grades are sealed, says spokesman Stephen Morisseau.

When GIA was recently asked to double-check a sealed stone, it discovered that the gem did not match the grades and description on the accompanying label. GIA has enlisted a corporate investigator to examine the situation.

A statement adds clients with concerns about whether a sealed diamond matches the grade can submit their packets for a check to GIA free of charge.
