Open Letter from David Gavin Regarding Over Grading and Certification

November, 28, 2014

Dear Bourse Member,

The World Federation of Diamond Bourses president Ernie Blom put out an open letter on diamond grading, on Nov. 21, 2014.

As Canada`s only diamond trading organization and on behalf of the Board and with regard to this issue, the Diamond Bourse of Canada is fully supportive of the WFDB`s stance on the overstating of grading and we are in agreement on the terminology in regards to this matter.

The DBC recognises the need for increased transparency and honesty in the manner in which diamonds are traded and sold to consumers.

We advise all our members to adhere to the DBC code of ethics and to act at all times, in accordance with the highest standard of business ethics, personal integrity, honesty, including business practices that do not mislead or deceive.

As a Bourse member and supplier, it is your responsibility as a seller to ensure that the diamonds you sell are accurately graded to the standard accepted in the global diamond industry, which is the GIA.

As Mr. Blom stated, “ethical grading and certification are the most basic principles of the industry and these cannot be compromised. “
Sincerely,


David Gavin, President
DIAMOND BOURSE OF CANADA

Blom: Open Letter Regarding Over-Grading Certification
(Rapaport, By Ernie Blom)

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.

Recently, awareness was raised regarding problems existing within a specific laboratory group and the overstating of grading from certain laboratories in this group, which has led to the exclusion of said laboratories certificates by the Rapaport Group.

Honest Grading
Overgrading is not just a legal issue, it is an ethical issue facing the diamond and retail industry.
(Rapaport Magazine, Martin Rapaport)

Is it okay to sell a diamond as a G color when the color is really an N? How about if the G is really an L? Shockingly, a lot of the people in the diamond trade think that it’s perfectly okay to use third-party diamond grading reports to overstate the color and clarity of the diamonds they sell.

GIA Develops, Will Sell Synthetic Diamond Detector

GIA Develops, Will Sell Synthetic Diamond Detector

The instrument, called DiamondCheck, uses stereoscopy and works in combination with recently developed GIA software that interprets the data. So when a stone is put into the machine, it will tell the user if it is “natural and untreated,” “not diamond,” or “further testing [is] needed to determine treatment or synthesis.”

De Beers Canada presents the DTC Diamond Sure™ to the Diamond Bourse of Canada

Upon it’s opening, in January 2010 the Diamond Bourse of Canada was generously presented with the DTC Diamond Sure™ from De Beers Canada. In the photo Bhushan Vora, Founding Chairman Diamond Bourse of Canada and President at Gem Star Inc. receives the DTC Diamond Sure™ from Jim Gowans, currently CEO, Debswana, De Beers .

All Bourse members, are welcome to test stones using the equipment in our gemmological technology facility. Two great and easy to use instruments for testing for Synthetics and Color Treatments are the DTC Diamond Sure™ and the HRD D-Screen.

DTC Diamond Sure™

Well-conceived and highly effective synthetic diamond detection instrument, developed by the Diamond Trading Company (DTC) in London. The Diamond Sure™ does the initial screening, based on research with hundreds of thousands of samples, and can distinguish between natural diamonds and synthetic ones or simulates. The device is easy to use, and gives sharp results:

A diamond will either pass the test or be recommended for further examination.

With the current news about synthetics in the market, members are more frequently testing their diamonds at the Bourse with the DTC DIAMONDSURE™. While testing, we discovered a Type Iab diamond.

We now understand that the DTC DIAMONDSURE™ can indicate the possible type of diamond it is testing.

Another 50 stones were tested and discovered two (2) Type II diamonds that were a D colour.

Not all stones though that are flagged by the DIAMONDSURE are synthetics; rather they display indicators that warrant further examination, such as a possible Type Iab or a possible Type II without further laboratory testing.

Around 98% of colourless and near-colourless diamonds will ‘PASS’ and require no further examination.

All synthetics, simulants and around 2% of natural diamonds (type II and IaB) will be indicated and register as ‘REFER FOR FURTHER TESTS’.

HRD D-Screen

  • A Compact Practical, and Affordable Test for Synthetic and Color Treated Diamonds
  • Operation is really simple: Turn the instrument on and watch it perform its self-check.
  • Then simply place a polished diamond over the sensor, close the cover, and in a few seconds the D-Screen gives its reading.
  • Green means the diamond can definitely be considered natural and not colour enhanced
  • Yellow indicates that the stone should be sent to a gem lab for more elaborate testing
  • Stones can be tested almost as fast as you can place them into the unit
  • To save power the unit shuts itself off automatically after five minutes
