Why Didn’t Synthetic Gemstones Kill the Natural Gem Business?

June 30th, 2014|0 Comments

There are those, particularly in the consumer media, who predict that the arrival of lab-grown diamonds will kill the market for natural gemstones. After all, why would consumers pay less for what is essentially the same product, just produced by a different means? Still, the natural trade can point to a notable counterexample: The market for lab-grown colored stones never killed the market for naturals. Which got me thinking: Why is that? And are there any lessons that the… …read more

Can Lab-Grown Diamonds Be Called Eco-Friendly?

June 19th, 2014|0 Comments

During the Natural Color Diamond Association panel on synthetic diamonds at the JCK show two weeks ago, Jewelers Vigilance Committee president and CEO Cecilia Gardner said something I found quite surprising: Calling a lab-grown diamond eco-friendly might not be permissible under the Federal Trade Commission’s standards for so-called green claims. That lab diamonds are eco-friendly is a regular contention from diamond growers. A rotator slide on the front page of Gemesis’ site declares… …read more

EGL USA: “We’re Different”

May 24th, 2014|0 Comments

Earlier this month, a Tennessee TV station slammed a local store for using reports from EGL International, a lab that it claims has lower grading standards. (EGL International did not return a request for comment on that report.) That report found a receptive audience in EGL USA, which has been engaged in an eight-year legal battle with other EGLs stemming from its attempts to have overseas EGL reports banned from U.S. shores. That case went to trial in June 2013, but no decision has been issued… …read more

Are Synthetic Diamonds a Threat to the Natural Industry?

April 18th, 2014|0 Comments

Last week, Israel Diamond Exchange unveiled a new slogan: “Natural is real.” The slogan is a clever play on the word Israel, and a less-clever poke in the eye to lab-grown diamond producers, who do, in fact, produce real diamonds. This comes on the heels of the bourse’s decision to ban synthetics from its trading floor. (Interestingly, the exchange first banned lab-grown gems 10 years ago. So it’s not clear if this is a re-ban or a clarification of the existing one.) These incidents make… …read more


Meet Bluedax, the RapNet for Rough

April 14th, 2014|0 Comments

There’s a lot of talk about whether rough should be traded in Antwerp or Dubai. But in the last year, a new market has emerged that could prove equally significant­—online.

After 35 years as a rough broker, Guy Harari says he first got interested in an online trading platform when he sat in his office and had an epiphany. “I’m thinking, how come I can’t go on my computer and see what’s going on [in the rough market]?” he says. “Why do I have to travel all over the world, call all sorts of… …read more


De Beers Entering Synthetic Diamond Market?

April 7th, 2014|0 Comments

Promoters of synthetic diamonds often argue that if all diamonds are grown in a lab, it would eliminate blood diamonds. The problem with that logic, which is recognized by most NGOs active on this issue, is that it would wipe out the market for good diamonds, too. As most of the industry is well aware—even if most of the outside world is not—diamond mining has turned Botswana into one of the most prosperous and stable nations in Africa. The movie Blood Diamond caused considerable anxiety in… …read more


GIA Develops Synthetic Diamond Detector

January 24th, 2014|0 Comments

GIA has developed a much-needed machine to help detect if a diamond is natural, or possibly lab grown or treated. With the increase in synthetic (man-made, lab-grown) diamonds in the market place, some of which are going unidentified, this is good news.

The instrument is called DiamondCheck, and uses stereoscopy 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 one of three results

  1. “natural and untreated”
  2. “not diamond”
  3. “further testing [is] needed to determine treatment or synthesis”

Unfortunately, GIA also makes it clear that this is not the long-sought-after […]

AGS is Changing the Market

AGS Cut Grades Changing the Market

AGS is soon changing the entire landscape for the diamond market, from cutters of the rough all the way up to the final consumer that wears the finished diamond on her hand. This is going to be announced to the public in August I think, but we are hearing about it already in the trade.

The change has to do with the way they are going to grade the cut of a diamond. Actually, what makes it such a big change, is that they are not going to grade the cut now. Rather, they are going […]
