Lab Grown White Diamonds are Available Now

Do you know the diamond color grading scheme? It starts from D, runs to Z and is applied only to colorless diamonds as far as fancy colored diamonds have their own grading scale. So, D refers to absolutely white stones while Z is used to identify brownish diamond.

In fact, most diamonds produced in the laboratories are usually tinted from faint yellow to intense brown, while colorless diamonds are rather the exception. But as far as you can notice majority of women prefer white diamond engagement rings, it means the demand for colorless gems is higher than for yellowing diamonds. To satisfy it, the world’s leading diamond laboratories directed their efforts on improving diamond growing technologies in order to produce flawless tintless diamonds. If you are looking for one then you should pay attention to the following information:

Gemesis’ decision to produce lab-created colorless diamonds and sell them over the Internet—at prices far more aggressive than some were expecting—may turn out to be a milestone moment for the synthetic sector. Partly as a result of Gemesis’ announcement, and partly because of improving technology, diamond producers are looking more and more into creating “white” gems.

“Their announcement has made other growers try and adjust their marketing,” says Tom Chatham of Chatham Created Gems. “The Russians are now moving their production to whites, and trying to be price-sensitive.”

Certainly the other companies openly producing these stones—and Chatham says there is a lot going on under the radar—are increasingly talking about their colorless production. Erik Franklin, president of Greenville, S.C.–based D.NEA, which recently set up the world’s first created diamond retail store, says that’s where his focus is now. “We have 40 to 50 whites and a lot more coming,” he says. And Scio Diamond, which bought the former assets of Apollo Diamond, plans to produce mostly “light colorless” stones and “bubblegum pinks,” says company CEO Joseph Lancia.

Not surprisingly, Gemesis’ announcement sparked articles predicting these gems will spell doom for the natural diamond sector (even though the company’s rollout has been rather low-key, at least compared with what we have seen in the past). But we are talking about extremely small numbers here, compared to the over 100 million carats of natural diamonds produced each year. By contrast, Gemesis only has 3,400 or so colorless diamonds for sale.

We are also talking about small sizes. It remains quite challenging to produce colorless gems of significant caratage, particularly with the CVD method, which tends to grow things flat. The largest stone Gemesis currently lists is a 1.27 ct. princess. All in all, we are long way from the point where notable diamonds can be churned out by machines. (It seems counterintuitive that it’s harder to produce a big diamond in a lab than from a mine. But it’s so.)

Still, no matter what happens with Gemesis’ little experiment—and CEO Stephen Lux tells me he is “exceptionally pleased” with the initial reaction—the lab-grown sector appears ready to embark on a new phase, after nearly two decades of delays.
