Lab Created diamonds Are like real thing says producer

DCLA DTC DiamondView

Consumers can now save thousands of dollars on diamonds, with a technological breakthrough that allows Synthetic diamonds to be created in a lab.

Bissell said the lab diamonds are not different in any material way and have all the optical, chemical and physical properties of mined diamonds, and they’re 100 percent carbon because they’re genuine diamonds.

The lab created diamonds are grown in pressurized containers on a small piece of carbon known as a seed,. The ultimate result is a high quality Synthetic diamond with the same properties as a natural diamond.

John King of the Gemmological Institute said lab grown diamonds are essentially the same as natural ones, and it’s just a matter of educating consumers.

To keep up with the new technology equipment to test stones and prove natural or synthetic is available at laboratories.

Created diamonds do come with certification from some laboratories with regard to colour and clarity.

In Australia DCLA does not certificate treated or synthetic diamonds and guarantees all diamonds ever submitted have been tested and are natural as stated on the certificate.

NOTE: If you have a certificate or report which does not say the diamond is natural, it has NOT been tested.

Open letter regarding over grading certification from the WFDB


Colleagues and friends,

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.

Your attention is drawn to the following issues:

(a) Ethical grading and certification are the most basic principles of the industry and these cannot be compromised.

(b) As part of the sales transaction the seller of diamonds provides a guarantee to the buyer of what is being sold and this forms a binding contract between the two parties. The seller cannot later hide behind an overstated grading report claiming ignorance as he/she will be held responsible regardless of any grading report supplied with the diamond(s) being sold. Diamantaires cannot hide behind certificates with the excuse that these goods sell cheaper. There is a common standard of colours and purities, and it is not about price but quality.

(c) In blatant cases the misrepresentation can amount to fraud with criminal consequences, depending on a countries consumer laws.

(d) Member Bourses must implement action in countries experiencing this kind of practice:

(i) If the offending party is a member, then the bourse concerned should take action under its own rules.

(ii) If the offending party is not a member, then the bourse concerned should report it to that countries consumer rights regulator in order to protect consumers rights..

On behalf of the Board and with regard to this issue, I commit the WFDB to ensure that we resolve matters as quickly as possible. We cannot reserve our position whilst this kind of practice prevails from a few laboratories that are damaging the entire diamond industry. Decisive and immediate action is required to eliminate this practice and the WFDB is in terms of its mandate compelled to take the lead. To this end a meeting will shortly be called of all the major laboratories to find common ground on the way forward.

I call on all responsible stakeholders across the world to stand together to eliminate this practice as it will harm our industry in a way that could dwarf any previous problems faced by the diamond industry.

I look forward to your full and ongoing support in this matter.

Synthetic or Lab grown Diamonds

DTC Diamond View at DCLA Laboratory

The question is how many synthetic or Laboratory grown Diamonds are there in the market.

The Gem and Jewellery Export Promotion Council estimated current laboratory created or synthetic diamond production at 350,000 carats per year.

A report on laboratory grown diamonds by Frost and Sullivan, estimates that synthetics currently constitute up to 0.6 percent of the total value of the polished diamond market or up to $135 million by value. With a anticipated three percent growth in two years.

In 2013 there were numerous reports of undisclosed Synthetic stones discovered at laboratories with the technology to identify the Synthetic diamonds.

Since De Beers and the GIA introduced new testing machines and De Beers launched an Indian testing service, the trade is more protected.

In Australia DCLA has tested every diamond ever submitted to the DCLA laboratory.

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.”

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.

Synthetic Diamond warning.

WFDB Warns of Not Disclosing Synthetic Diamonds

The World Federation of Diamond Bourses (WFDB) has noted with concern the growing tendency of undisclosed synthetic diamonds to enter the market.

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.

De Beers August Sight Estimated at $520M

  De Beers site
