WFDB president Ernie Blom reacts to GIA warning

World Federation of Diamond Bourses (WFDB) president Ernie Blom has expressed his concern over the discovery of undisclosed treated diamonds.

This follows a statement from the GIA that around 500 colourless to near-colourless diamonds were submitted to the GIA’s grading laboratory in Ramat Gan, Israel, with potentially a undisclosed temporary treatment.

The GIA believes that the treatment temporarily masks the body colour of the diamond, resulting in a colour grade that can be up to three grades higher than its actual grade.

The GIA said it ended client agreements with the companies that submitted the diamonds and notified the relevant trade bodies.

Ernie Blom released the following statement…

“I am extremely concerned by this development. This is clearly unlawful behaviour. We will have no tolerance whatsoever for this type of alleged illegal activity.

“It is crucial that this kind of unlawful action is stamped out. We are pleased that the GIA publicised this development so that diamantaires can be on their guard, and that the IDE is moving firmly in order to deal with this issue with the utmost seriousness.

“Our industry must come together to counter such activity, both for the good of our members and for the end-consumer who is always uppermost in our minds.”

The report numbers of the potentially treated stones are posted on GIA’s website, and anyone who has purchased or has access to any of these stones is requested to submit them to any GIA lab for a no-cost, accelerated review.
