Six More Arrested in GIA Hacking Case
Six more people have been arrested in relation to the hacking of Gemological Institute of America (GIA) diamond-grading reports by outside parties as the investigation into the case continues.
A total of eight arrests have now been made as a result of cooperation between the GIA, the Indian authorities and Tata Consultancy Services (TCS), the contractor that supports GIA databases, according to a GIA statement January 26.
In another development, the GIA has extended its submission date for the confirmation service for members of the trade concerned about the validity of their grading reports by two months to March 31, 2016.
Members of the trade with a GIA report originally issued between November 2014 and October 2015 who are concerned about its validity may submit the original report and the referenced diamond to any GIA location at no charge by the new deadline.
To date only 297 of 1,042 invalidated reports have been returned to the GIA. As of November 26, only 175 of the reports had been returned and two arrests had been made.
“It is imperative that all of the diamonds and their reports be returned to GIA to remove the fraudulently altered reports from the market,” the statement said.
De Beers first sight for 2016 is $540 million USD
De Beers the sold $540m worth of diamonds in its first of sale of the year more than double the value of the sales achieved in the final sight of 2015.
Prices for rough diamonds softened last year because of an oversupply of diamonds in the production centres forcing companies such as De Beers and Alrosa, to cut their supply of rough to the market in an effort to restore prices.
Rough diamond demand broadened across the entire range as cutting and polishing factories began to increase their production.
De Beers has said it will change the way it operates its sights to become more flexible and responsive to its clients.

‘Harsh’ prison sentences given in bribery case.
Antwerp The Correctional Court in Antwerp handed down “extremely harsh” sentences and levied “substantial fines” against four diamond traders accused of bribing a grader at HRD Antwerp to give their diamonds higher color grades than they deserved.
The Antwerp World Diamond Centre (AWDC) announced the sentences via a press release circulated Monday titled “No mercy for those involved in certification fraud.” On Tuesday, an AWDC spokesman said that the traders received up to 30 months in jail, 15 of which is effective immediately.
Although the AWDC is not releasing their names, the spokesman did reveal that three of the traders are from India--from Surat, Bhiwandi and Mumbai--and were managers of Belgian diamond companies. The fourth is from Sierra Leone.
The grader, whose name also is being withheld, received a “heavy” sentence as well, 18 months in jail, 9 of which is effective immediately, and a substantial fine in the case.
The AWDC did not have specific information on the amount of the fines. Judicial authorities in Antwerp could not immediately be reached for further comment on the case.
The HRD Antwerp grading bribery case dates back to March 2012, when news first surfaced that the lab fired a total of four graders for what it called at that time an “unprofessional act.” That June, a total of four people--reported to be two diamond traders, an HRD employee and a “facilitator”--were arrested in connection with the case.
The AWDC said there is another firm allegedly involved in the case and that the public prosecutor in Antwerp is submitting an appeal to enable this firm to receive an “even heavier” sentence.

$19.3m for the 357 carat rough diamond
Gem Diamonds LTD has sold the 357 carat exceptional white diamond recovered from the Letšeng mine for $19.3 million USD.
Gem Diamonds owns 70% of the Letšeng mine in Lesotho and 100% of the Ghaghoo mine in Botswana which is producing the exceptional rough diamonds.
The 314 carat diamond recovered in May 2015 sold in June 2015, and the 357 carat diamond which sold on the Antwerp tender last week for $19.3 million.
Both rough diamonds achieved top prices in the current market showing price resilience of large top quality diamonds.
Producing four of the twenty largest white gem quality diamonds ever recorded, Letšeng mine is renowned as highest dollar per ct kimberlite diamond mine in the world.
IDC Diamond Grading Laboratories use cold laser, this is why.
It is important to understand there are two very different categories of lasers used for diamond inscription; hot lasers and cold lasers. Hot lasers are YAG lasers and Cold lasers use Excimer laser technology.
Simply put the PhotoScribe Cold laser system is the only laser system guaranteed 100% safe for diamond inscriptions.
Hot lasers will chip or fracture diamonds. High quality polished girdles are especially at risk for fracturing or chipping with "Hot" lasers.
The picture is a classic case of the damage done by hot laser. This will lower the value of your diamond by changing the clarity grade or polish grade of the diamond.
Make sure your diamond is Cold Laser inscribed before you buy it.

ISO International Standard, welcomed by CIBJO
All laboratories must have DIAMOND on the report or certificate.
DIAMOND is used exclusively for diamonds of natural origin. In layman’s terms, if your diamond certificate or report does not state clearly DIAMOND IE: NATURAL DIAMOND on the certificate then is not compliant or working to Cibjo or IDC rules adopted by the ISO. This means the laboratory has not tested or proven the stone to be of natural origin.
MILAN, ITALY: JULY 27, 2015 - CIBJO has welcomed the publication of ISO International Standard 18323, entitled "Jewellery - Consumer confidence in the diamond industry," which specifies a set of permitted descriptors for the diamond industry that are designed to be understood by consumers. The new ruling by the International Standards Organisation explicitly defines a diamond as having been "created by nature" and further notes that "the denomination 'diamond' without further specification always implies 'natural diamond.'"
The new ISO International Standard mirrors the definitions outlined in CIBJO's Diamond Blue Book, which are aligned with those of the International Diamond Council (IDC). The Diamond Blue Book, the IDC Rules, and also the PAS 1048 documents, relating to terminology and classification of grading polished diamonds that were developed by CIBJO with the support of the German Standards Institute (DIN), were cited as the primary sources in the ISO International Standard's bibliography.
See: how to read a DCLA certificate. DCLA diamond grading reports are only issued for natural untreated and unenhanced diamonds. Therefore every diamond report issued by the DCLA has the term NATURAL DIAMOND clearly noted at the top of the certificate.
De Beers sightholders refuse boxes Update
De Beers’s the world’s largest rough producer felt the pain, when only $300 million of the $450 million estimated sight was taken up by their sightholders. This leaves 30 percent of the rough on offer on the table.
Anglo has previously counted on diamond revenues to offset a collapse in the price of other metals and minerals it mines. Anglo may cut the company’s dividend for the first time since 2009 according to analysts.
This is an indication of turmoil in the $80 billion diamond industry as traders, cutters and polishers suffer from a poor liquidity and weaker demand for jewellery.
Producers in India, where 90 percent of rough diamonds are cut and polished, may halt imports over the supply glut.
Update: Report sightholders may have refused 35%-50% at July sight which may be as low as $200M.

Arbitrators to Weigh Cases Involving GIA Grading Reports
Shmuel Schnitzer IDE's president, said The Israel Diamond Exchange will appoint arbitrators deal with transactions of treated diamonds certified determined by the Gemmological Institute of America (GIA).
He explained that the bourse decided it would enable arbitration hearings to restore business confidence and given the lack of any significant updates in the GIA's investigation.
The GIA issued a laboratory alert on May 12 recalling diamond grading reports for diamonds suspected of having undergone a ‘temporary’ colour treatment.
The GIA voided reports which GIA said had undergone undisclosed temporary colour treatment, and offered free of charge to regrade the stones in question.
The IDE banned members from trading the stones using the old GIA reports.

Kimberley diamond mines up for sale by De Beers
De Beers Diamond mining Groups Kimberley Mines are no longer in the company's strategic plan.
De Beers has been mining at Kimberley South Africa for more than a century, said it hoped to conclude the sale in a matter of months. De Beers produced 722 000 carats of diamonds at Kimberley in 2014.
In 2011 De Beers moved the whole of the company's sales operation which was London based to Gaborone in Botwana,
Anglo American planned to cut diamond production this year due to lower demand and prices, since late 2014 due to in most part to liquidity problems.
Hundreds of diamonds recalled by the GIA
Diamonds certified by the GIA had an undisclosed treatment which fades over time, but improves their colour by as much as three grades.
GIA is asking anyone in trade stocking these potentially treated stones to turn them back into the GIA for re-examination.
The majority of the GIA certified diamonds are one carat or larger, with a number of three to five carat diamonds. A colour grade of three higher in these sizes amounts to a very big difference in price.
GIA has terminated the client agreements with companies suspected of knowing the diamonds were treated and did not disclose it.
GIA discovered the treatment when a client who purchased one of the diamonds resubmitted it to GIA for re-check.
It was then that the GIA connected this stone with hundreds of treated diamonds submitted by the companies.
The GIA has notified industry bodies about the still unidentified temporary treatment.

SA diamond trader gambled the money away
An unnamed diamond trader is suspected of stealing diamonds valued at around US$1 million from several dealers in the Johannesburg diamond center in South Africa, according to a report in The Star.
The diamonds were apparently handed over to the diamond trader with the expectation that payment for them would be made within a few days, as is the custom in the diamond trade. The news source says an industry insider told them that the man was known to have a gambling problem and it was discovered that he had pawned the diamonds and gambled the money away over a period of two weeks.
The diamond trader is said to be in hiding, and his life is believed to be in danger.
South African Diamond Dealers Club Treasurer Michael Ellis is quoted by the news source saying that he is aware of the incident, and that the man is not a member of the Diamond Dealers Club, although he is known within gem circles. "You get a few incidents like this ever so often, but it happens with fringe members, not mainstream dealers," said Ellis, as quoted by The Star, adding that when any theft takes place, a ban on the dealer is placed worldwide, meaning that they will never be able to work in the industry anywhere in the world.
Debswana to cut output
Debswana's Managing Director Balisi Bonyongo said, the Diamond Company will cut diamond production at its mines as the company tries to match demand in the short to medium term.
The company would prefer to keep the diamonds in the ground until the market to recovers.
Bonyongo said that the company expected the market to return to normal after it slowed in the last year. In part due the liquidity constraints in India.
Hatton Garden Safe Deposit robbed
According to the police, robbers used heavy cutting equipment to break into the vault at Hatton Garden. The vault founded in 1954 is in use by almost 300 diamond and gold dealers and more than 50 stores.

Tough rules for De Beers diamond customers
Biggest reforms in a decade from De Beers’s over concerns of the financial stability and transparency of their sightholders.
The world’s largest supplier by value is changing the deal, introducing tougher rules for companies wanting to join its coveted group of sightholders.
De Beers will also insist customers hold a specified proportion of equity in their businesses, making them less reliant on bank borrowing.
Bank finance has receded and no new banks are coming forward after Antwerp Diamond Bank closed to new business in September. Over the past two years banks have cut credit lines to the diamond trade, causing liquidity problems and a sharp fall in rough diamond prices.
The De Beers group which sells $6bn of unpolished diamonds annually will clarify the financial situation of all the companies. The belief is transparency will benefit the whole sector.
Trillions of carats of diamonds from meteorite

Brown Diamonds natural or synthetic
Causes of colour in heat treated brown diamonds and synthetic brown diamonds are similar to treated pink diamonds.
In natural diamond the colour is related to a lattice imperfection. This can be mimicked in synthetic or treated diamond by a variety of treatments including annealing, heating or irradiating. The heat and pressure or irradiation can result in the lattice deviation resulting in the brown or pink colour.
Synthetic brown diamond is created by compressing graphite under extreme pressure and heat to above 1500 Celsius. The treatments were perfected in several laboratories in Russia, United States and China.
Lazare Kaplan Internationals Belgium subsidiary Pegasus Overseas Ltd marketed the General Electric processed diamonds under the name GE POL or in the USA as Bellataire.
This led to a technique for creating, or treating brown diamonds into higher valued colours like yellow or colourless diamond.
The disclosure of the treatment is noted by the “GEPOL" inscribed on the girdles of every treated diamond.
Brown diamonds are often marketed with expensive sounding names like Cognac, Champagne or Chocolate diamonds. Natural brown diamonds are a cheap alternative to more expensive colours.
Threat to Profitability from Synthetic Diamonds says De Beers
The flooding of synthetic diamonds in the industry is threatening long term sustainability of Rough and Polished.
Bruce Cleaver Head of Strategy and Corporate Affairs said “duds” were threatening profitability. And the impact of synthetic diamonds is more severe when manufactures don’t disclose Synthetics to the market.
