Even GIA doesn’t have the answer of Mystery Diamond Color. There are around 500 diamonds with uncommon color which is marked as Mystery Diamond by GIA.
The Gemological Institute of America reported that “as many as 500 diamonds may have been subjected to a new mystery color treatment that temporarily improved the stones’ color as much as three grades.”
GIA believes that the treatment temporarily masks diamond’s body color, resulting in a color grade that can be up to three grades higher than it would be normally.
According to spokesperson Stephen Morisseau, GIA first became aware of the tricky treatment after grading some 500 stones submitted by Israeli manufacturers over a series of month.
Mr. Morisseau says that “We reasonably believe these stones were treated in some way” and he also added that “We don’t know what the treatment is, we are actively researching it?”
GIA said in lab alert “We ask anyone who has purchased or holds these diamonds to please resubmit them to any GIA location for review. GIA will expedite the service, and no fee will be assessed.”
L.Y.E Diamonds, E.G.S.D. Diamonds, Romok Abramov, and Yair Matatov these four companies are banned by GIA. After this action by GIA only one company replied which was Romok Abramov? Abramov says ““All the stones mentioned in the GIA report are not mine, I Never saw any of those stones and don’t have any idea if they were treated.”
The World Federation of Diamond Bourses involved and sent statement expressing concern about the incident. The president of WFDB Mr Ernie Blom said that “This is clearly unlawful behavior, we will have no tolerance whatsoever for this type of alleged illegal activity. We are pleased that the GIA publicized this development so that diamantaires can be on their guard.”
