The GIA has invalidated grading reports for 1,042 diamonds submitted primarily to its grading laboratory in India. An outside party who gained unauthorized remote access to GIA’s grading information database altered the reports. The list of invalidated reports is available on our website.
The investigation regarding the GIA certificates for around 500 diamonds that underwent a color treatment process is continuing, the Israel Diamond Exchange (IDE) said in a notice.
The enquiry is being led by authorized bodies and according to the picture that emerges, the IDE will decide how it proceeds with the issue.
The diamond industry is facing a serious challenge to its integrity which could lead to major consumer confidence problems, if diamonds are sold with overstated certification. I want to stress that this is an industry problem that must be resolved by the industry in order to retain consumer confidence in our product and sustain and develop the international diamond trade.
EGL International Managing Partner and CEO Guy D. Benhamou said he categorically refutes claims made on a regional television station in the United States that EGL’s grading standards were lower than those of its competitors.
“It is well known that since gemology is not an exact science, the same diamond sent to several gem labs could produce different grading results,” Benhamou said in a statement.
HRD Antwerp is launching the 16th edition of its international diamond jewelry design completion- with yhis year’s theme being “A la Carte – A Culinary Journey.”
HRD Antwerp says the theme aims to “encourage designers to produce sparkling and copious jewelry, seasoned with diamonds.”
World Federation of Diamond Bourses President Ernie Blom has praised the EGL International laboratory in Israel for its “vigilance” after the lab discovered four synthetic diamonds in a parcel of 20 stones submitted by a long-time client.
The HRD Antwerp gem lab has contributed one of its sophisticated D-Scope microscopes to the Technology Wing of the Israel Diamond Exchange.
The microscope, fitted with optics from the famous Zeiss company, features special lighting and a safe vacuum that holds the diamond.
HRD Antwerp was among the sponsors of the Third US & International Diamond Week which took place at the IDE last week.
