Carlsbad, Calif.--Two former employees of Tata Consultancy Services (TCS) are in police custody in connection with the 1,042 Gemological Institute of America diamond grading reports that were altered after individuals allegedly gained unauthorized access to the lab’s grading information database. 

In addition, the GIA said Monday that police have informed the lab that it may now publish the client accounts that submitted the diamonds in question.

The list of all 1,042 invalidated reports--along with the names of the 19 client accounts that submitted the diamonds connected to them--can be downloaded here on the GIA’s website.

The list includes the number and issue date of the invalidated reports and the shape and weight of each diamond, along with the submitting client account names. What the list does not include is color or clarity grades, as those may have been altered.

All 19 client accounts remain suspended from submitting stones to the GIA as the Indian police investigation continues.

The lab “strongly requests” that anyone in possession of any of these diamonds and grading reports return them immediately to the lab for examination at no charge. 

GIA circulated a trade notice Friday afternoon stating that one or more now-former employees of TCS, the contractor that supports it databases worldwide, gained “unauthorized remote access” to GIA’s grading information database and altered the color and/or clarity grades on some 1,042 diamond grading reports.

Most of the stones attached to the grading reports in question were submitted to the GIA’s lab in India in July and August, and were graded in full or in part at other GIA labs, including New York and its headquarters in Carlsbad.

The GIA said that the individuals involved were acting “at the behest of other parties unrelated to GIA or TCS.”
