Laboratory Breakthrough Creates Ideal Man Made Diamonds

Gemologists agree that Diamond Nexus Labs lab-created diamonds are glittering and brilliant because they come closer than any other gem material to matching, often besting the characteristics of mined diamonds.

They are so ostensibly close to mined diamonds that only a trained eye can differentiate the two, often requiring a microscope or loupe, picking out the mined diamond by its blemishes (inclusions). Consequently, many jewelers must use scientific testing equipment to make the distinction. Most people, even trained gemologists, cannot tell the difference with the naked eye.

For serious consideration, Diamond Nexus Labs manufactured diamonds must be compared by using the same properties evaluations as the mined diamond industry—The Legendary Four C's:

Color: The Gemological Institute of America (GIA) appoints color classifications of “D” through “Z.” Colorless diamonds, “Ds,” are extremely scarce in nature and they are representative of the peak of color grades—slight tints of yellow make diamonds less rare, grades “J,” “K,” “L,” & “M.” Diamond Nexus Labs cultured diamonds are always pristine clear transparent “Ds.”

Clarity: This is the degree to which a diamond is free of inclusions that hamper luminosity. Virtually every mined diamond has some internal or external structural flaws. Diamond Nexus Labs man made diamonds simply do not, and meet the rigorous standards of first-class quality.

Cut: The art of diamond cutting has been refined to precise mathematical formulas. A good cut is determined by its light reflecting properties and its light dispersion. The cut actually refers to two separate aspects of a diamond's appearance: (1) shape, and (2) quality of workmanship. Diamond Nexus Labs' synthetic diamonds are precision cut perfectly to the optimum number of facets.

Carat-weight: The size of a diamond is measured in carats; one aspect in the cost of a mined diamond is size. Price is also determined by the Color, Clarity, and Cut—the greater the quality, the higher the per-carat price. Small mined diamonds are more abundant that large ones, so bigger stones command a great per-carat price. A 3-carat diamond of similar quality could be priced 20 times that of a 1-carat diamond. Diamond Nexus Labs flawless man made diamonds are all the same low price per carat. Size never influences the per-carat price!

De Beers sees less threat from fake diamonds

A competitive threat posed to the diamond sector by synthetic gems may be neutralised as the artificial stones become more useful -- and more valuable -- in the electronics industry, an executive of the diamond giant De Beers said on Tuesday.

The prospect that firms could flood jewellery markets with cheap, look-alike synthetic diamonds has been lurking in the background as a possible threat for years, but Jonathan Oppenheimer told a mining conference in Cape Town that the future looked brighter now.

"Synthetics is a terrifying prospect for the natural diamond industry," he said. "They are a potential threat, but entirely manageable."

Research is now focusing on using synthetic diamonds as a base substance in semiconductors in the electronics industry, Oppenheimer said.

"That is very exciting, that is something that I believe a whole bunch of people...are pursing vigorously and a huge amount of money is being spent in research laboratories around the world to perfect that. Not a lot of money is going into possible jewellery substitutes," he said.

"What I am hoping , and we're very much involved in the synthetic diamond business, is that the synthetic value proposition will move synthetic diamonds to higher value products than jewellery."

Oppenheimer, who heads the South African unit of De Beers, said the company was also confident that detection systems would always be able to differentiate between manufactured diamonds and natural ones.

"We feel very confident as a company that synthetic diamonds are 100 percent detectable," he said.

De Beers, which is the world's biggest diamond producer and controls nearly half the world's supply, is 45 percent owned by Anglo American with the Oppenheimer family the other major shareholder.

Synthetic diamonds on the way

Man-Made Diamonds Gain In Popularity

They sparkle, shine and shimmer, but buying a real colored diamond can break the bank. That's why man-made diamond doubles are gaining in popularity.

When the legendary Marilyn Monroe sang of her love for diamonds, she was no doubt raving about the real thing, but today's girl may have found a new best friend.

“It's what you call a fancy diamond. I love it,” said Gemesis customer Lupe Duran.

But this diamond is not the work of Mother Nature. Lupe Duran is wearing a man-made diamond produced in a Florida laboratory by a company called Gemesis. They start with the seed of a real diamond, apply high pressure and duplicate Mother Nature.

“Next to the real diamonds I have, they shine just as beautiful,” Duran said.

Gemesis specializes in fancy colored diamonds made popular by today's movie stars, but a Gemesis will cost 30 to 40 percent less than a real diamond. The lower price is what attracts most customers, but because of the quality, Horwitz jewelers proudly sells Gemesis right next to real diamonds.

“This is a diamond. It has the strength, the same characteristics of a diamond. It has exactly the same properties so if you envision that a diamond is forever, so is a Gemesis,” said Craig Horwitz
at Horwitz Jewelers.

“I certainly couldn't tell the difference,” Duran said.

A natural diamond costs $5,000 compared to its man-made counterpart priced at $2,000.

“An expert under a microscope will be able to tell the difference, but to a client, they will not,” said jewelry appraiser Harold Vogel. “In most cases i can spot the seed. I don't find any reason consumers shouldn't buy them as long as they understand that they're man-made.”

And Vogel says these man-made gems will hold up just as well as real diamonds.

“I hope he's right for the sake of the people who have spent so much money for a stone that's not real,” said Michael McGuire at Supreme Jewelers. McGuire, a jeweler, is obviously not a Gemesis fan.

“I don't know how anyone can show off a piece of jewelry and say this, of course, is not real, but it's very nice, isn't it?” McGuire said.

“Someone like myself and other customers, this is an alternative. You can still have color, but it's a lot cheaper,” Duran said.

Right now Gemesis only makes yellow and orange colored diamonds. However, according to the company's Website they will add more colors if there is a demand. Experts believe the company will eventually duplicate the popular "white" diamond.

German Court Bans 'Cultured Diamonds'

A Munich court has issued a restraining order against a German distributor of lab made synthetic diamonds produced by the Gemesis Corporation to stop using the term “cultured diamonds” when marketing its products to the public in Germany, saying the term is misleading.

From now say Gemesis'
synthetic diamonds

The case was brought against Gemsmart GmbH, a Munich-based distributor for Gemesis, by the Central Office for Control of Unfair Competition following an advertisement placed by the company in the local press, which stated that “…cultured diamonds have the same chemical, optical and physical properties as their counterparts that were created in the ground”.

The wording of the advertisement was similar to that used by Gemesis on its website, where it says: “Gemesis Cultured Diamonds are laboratory-created diamonds that have the same chemical, optical and physical characteristics as earth-grown diamonds.”

The court ordered Gemsmart to refrain from using the term “Cultured Diamonds,” or “Zuchtdiamanten” in German, which was the term used in the advertisement.

In future, the court said, the company can only refer to laboratory created diamonds as “diamonds” if the word is immediately preceded by one of the modifying adjectives, “synthetic” or “artificial”.

In reaching the decision, the judges relied on the terminology and definitions contained in the Diamond Book of CIBJO, the World Jewellery Confederation.

The judges also attached to their ruling an order that a financial penalty of up to €250,000 would be incurred for each case of non-compliance with the restraining order, adding that a jail term will be imposed on the manager of the defendant’s company if the penalty is not paid.

Legal commentators have suggested that since the ruling has taken place within the jurisdiction of a member country of the European Union, the verdict could have an impact on future rulings in other EU countries.

In the United States, the world’s largest jewelry market, the term “cultured diamonds” has not been challenged in court.

However, Cecilia L. Gardner, the executive director and general counsel of the New York-based Jewelers Vigilance Committee (JVC) wrote, “The Federal Trade Commission Guidelines for the jewelry Industry address the use of the term ‘cultured’ only as applied to pearls.”

“However,” Gardner continued, “it is the view of the JVC that the use of the term ‘cultured’ as applied to diamonds without additional information about how the product was created is insufficient disclosure to describe the true nature of a synthetic or laboratory grown diamond.”

CIBJO President Gaetano Cavalieri welcomed the verdict, emphasizing that the international jewelry trade had won a double victory in this case. “First of all, at a time in which we seek to protect, reinforce and strengthen the consumers’ confidence in natural diamonds and natural diamond-set jewelry, this is an important achievement. I am sure that soon, we will have an industry-wide consensus on the banning of the term ‘cultured diamonds,” he said.
