Diamonds not always a buyer’s best friend, dispute shows

EGL (European Gemological Laboratory)

Founded in Tel Aviv in 1974 and now with eight offices worldwide, EGL (European Gemological Laboratory) is the target in a lawsuit in US courts after claims of “over-grading” diamonds, certifying them as being worth more than they really are – a charge the service vehemently denies.

Whether the issue for EGL’s alleged over-certification of the diamonds is fraud – or the result of a decades-old difference of opinion on how to fix and rate the value of stones – will be for the courts to decide.

EGL suffered the latest blow this week when Martin Rapaport, chairman of the Rapaport Group, which publishes an authoritative diamond price list and table that is considered the standard for diamond pricing in the US, said that his service would no longer list stones evaluated and certified by EGL for the all-important “four C’s” that determine the value of a diamond – carat, color, clarity and cut. In a statement, Rapaport said that his service “is opposed to the misrepresentation of diamond quality. The over-grading of diamonds is an unfair practice that destroys consumer confidence and the legitimacy of the diamond industry.”

The brouhaha stems from a series of lawsuits against Genesis Diamonds, a retailer in Nashville, brought by several customers who claim they were sold overpriced diamonds. In one case, a customer paid $135,000 for two stones, one weighing 3.01 carats and the second 3.04 carats, rated as “excellent” and “very good” cuts by EGL. But another appraisal placed the stones a grade lower, at “very good” and “good.” That appraisal valued them at just $22,500. The case was covered on a local Nashville television station, which highlighted the issue of the EGL report. Since then, other suits have been filed against Genesis.

But EGL CEO Guy D. Benhamou said that the reports got it all wrong — the issue is not fraud, but subjective interpretations of what constitutes a “good” diamond. In a statement, Benhamou said that “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. You can receive different grades for the same diamond from several different labs. That does not mean that any of the diamond labs made a mistake, it is simply in the nature of the business. Any diamond grader and lab will tell you that.”

Funding Zimbabwe diamond mines risky

Zimbabwe Diamonds

Rand Merchant Bank (RMB) a leading South African bank said diamond mining ventures in Zimbabwe are difficult to fund because of the high political risk and uncertainty in the country.

DCLA is compliant and works strictly to the IDC rules.

As per the IDC rules the Synthetic diamonds Must be disclosed as “Synthetic diamond”.

If they do not issue grading reports, a short statement with weight, shape and nature of the stone must be available. The term “Synthetic Diamond Examination Report” or “Synthetic Diamond Assurance Report” is suggested for this limited document.

The terms laboratory-created/laboratory-grown/man-made/synthetic diamond may be used. The term “cultured” may not be used in any way to describe synthetic diamonds.

The DCLA will not certificate synthetic  diamonds or diamonds with reversible treatments as this could lead to confusion in the Australian market.

Where's the best place to buy loose diamonds?

General consensus is to definitely buy online.

Simple reason is online sales don’t have the expense of retail location, security and personnel.

All of these add to the cost of the diamond, but not the value.

But before you do buy, ask these questions.

Do all online diamond sellers ship free of charge?

Can you view before buying, if you wish? 

Is the diamond certified by an IDC or equally highly recognised Laboratory?

Is the diamonds quality guaranteed?  


Only at the DCLA Diamond Exchange the answer is yes to all these questions.

The Diamonds are certified by the best laboratories in the world and are Fully Guaranteed.

The shipping is Free across Australia.

And most important, a trained diamond grader will personally show you all the diamonds attributes, as well as explain all the details so that you understand and make an educated decision before you buy.

This is all done as a free service complements of the DCLA laboratory which is the only qualified and state of the art IDC Laboratory in Australia.

DMIA calls for all-industry, international meeting on misrepresentation of synthetics as natural diamonds


New York, November 12, 2013

Dear Colleagues,


Much has been written in the past month concerning synthetic diamonds being represented as natural diamonds. We at the DMIA believe that it is imperative that the industry respond immediately and forcefully.


DMIA issued a formal call to action 18 months ago in May of 2012 (reprinted below in its entirety) and do so again now. In our view, one of the major problems in attacking this issue is the lack of cohesion from stakeholders all of whom are rightfully very concerned.


As an industry leader DMIA is indeed making progress as we are in constant contact with local as well as Federal law enforcement agencies, the United States Department of State, and our domestic industry leaders; among them GIA, JA, AGS, MJSA, JVC, to mention just a few.


We once again call on the international and domestic leaders from industry, law enforcement, and laboratories to physically gather together as soon as possible and for as long as is necessary to finalize the best approach.


To that end, we reiterate today that we are ready to host a conclave in New York City and will work immediately with our colleagues to make it a reality.

The law is clear and the punishment for fraud will be pursued. The WFDB will work with all legal agencies across the globe to assist in the prosecution of those who participate in this type of fraud in the diamond industry.

DCLA is the only laboratory that guarantees all diamonds have been tested for treatments and natural origin. DCLA is the only laboratory working to the International Diamond Council (IDC) rules in Australia.

Buying Diamonds Online: Don’t Be Taken Advantage Of

DCLA Diamond Exchange

Let’s face it: everything you buy today in store is also available online, and often for far cheaper. While some thought it was a fad at first, Internet shopping is here to stay. These days, if you were looking at a pair of runners, you would be silly not to look at the online offers first!

At the DCLA laboratory, we are asked everyday, “How does this work with diamonds and diamond jewellery?”

While buying diamond jewellery and diamonds online may seem like a simple choice, the truth is that there is one huge difference that puts the online jewellery industry in the “customer-beware” box.  The difference is that when it comes to diamonds, you have no clue what you’re buying without an independent certification. If you buy a TV online, chances are it will be the same model, make and carry the same guarantee available at the store – but with a diamond, however, you have no idea whether what you’re paying for is what you really get.

When purchasing a diamond online or not, you should always ensure that it is covered by an IDC-recognised certification. The IDC rules are the internationally-recognised and accepted rules for diamond grading and diamond certification as set out by the WFDB, IDMA and Cibjo – the world’s highest authorities in diamonds and jewellery.

If you buy an IDC-recognised certified diamond from your trusted brick-and-mortar store, you will get the diamond you are expecting. It will undoubtedly cost more than purchasing online, but you will have a face to go with the purchase.

If you buy a diamond online, this is unfortunately a different story.

Local sites seldom own the goods listed. In fact the people trying to sell the diamond probably have never seen the diamond themselves.  This is because the diamonds are not always in stock at the particular store but are instead part of virtual lists populating the site from overseas sellers. These virtual lists are filled with stones that aren’t actually owned by the site you’re viewing them on. Hawked from overseas anonymous sellers, often there’s something seriously wrong with these diamonds that would make it impossible to sell them traditionally.

So are there any safe sites to buy from? Yes, certainly, if the goods listed are actually in stock and available immediately. Make sure you always check that the diamond has an independent diamond certification from a respected laboratory. That way, you’ll always know exactly what you’re getting. Also, never put a deposit on a diamond to be sourced or delivered and never buy a diamond without seeing it first.

Not all laboratories have the same grading system, equipment or official master stones for comparison.  This you will hear from all the recognised laboratories and the honest retailers and dealers. Armed with the correct information from an independent source, you can take charge of the diamond market whether online or off, and get the best deal for your money.

Professional valuers are put to the test

Synthetic diamonds

Two diamonds were sent to three Accredited Valuers for valuation.

The synthetic diamond pendant had valuations ranging from $4330 to $5700, which is up to $5100 more than its true value.

The man-made diamond ring ranged from $5350 to $6200, which is $5000 more than it's worth.

The Laboratory created man-made diamonds cost $600 and $1200. Neither of the Synthetics were identified as by any of the Accredited Valuers.

Synthetic diamonds can be created in laboratories by machines that work around the clock to replicate what occurs in nature, subjecting graphite carbon to extreme pressure and temperatures of up to 1500C, machines are able to produce a synthetic diamond in just a few days.

Or by Chemical vapour deposition (CVD) used to produce a synthetic diamond by creating the circumstances necessary for carbon atoms in a gas to settle on a substrate in crystalline form in a matter of hours.
