International diamond grading laboratory, the Gemological Institute of
America (GIA), has halted an international operation that was using
counterfeit GIA Diamond Grading Reports to support diamond sales,
chiefly via the internet.

The GIA filed a lawsuit in Chicago against Moti Weisbrot, the leader
of the counterfeiting activity, and others who participated in the
activities by either producing counterfeit reports or agreeing to sell
diamonds accompanied by the counterfeit documents. GIA is obtaining
permanent injunctions against the participants in these actions,
thereby stopping the counterfeiting activities.

All the diamonds sold with these counterfeit Grading Reports were
clarity enhanced. As a policy, the GIA does not grade clarity-enhanced
diamonds. Thus, the documents were not only counterfeited, but
represented diamonds that would not have received a GIA Diamond
Grading Report in the first place.

“The public places great trust in the accuracy and integrity of GIA
Diamond Grading Reports and we go to great lengths to preserve that
trust. The counterfeit reports in this case were intended to add value
to clarity-enhanced diamonds by manipulating the public’s reliance on
the GIA report. We took these legal actions in keeping with GIA’s
mission to protect the interests of both the public and the gem and
jewelry industry,” commented GIA President William E. Boyajian.
