Lucapa recovers first +100 carat diamond from Mothae

Lucapa Diamond Company has recovered its first+100 carat diamond for its Mothae mine in Lesotho.

The stone is a gem-quality 126 carat diamond and is the largest diamond recovered since commercial mining operations commenced in January 2019.

The diamond is also the sixth +50 carat diamond recovered since Lucapa commenced its pre-production bulk sampling programme at Mothae in 2018.

It comes shortly after Lucapa and its partners recovered a 130 carat gem-quality diamond from the company’s high-value Lulo alluvial mine in Angola.

Lesotho Minister of Mining, the Honourable Keketso Sello, said the recovery of the 126 carat diamond represented another milestone for Lesotho’s highly-prospective diamond sector.

“Lesotho is very proud of its international reputation as a producer of large and high-quality diamonds and this latest recovery from our newest mine, Mothae, continues to demonstrate our nation’s great potential,” said minister Sello.

Lucapa MD Stephen Wetherall said the 126 carat diamond was further proof of the large stone and high-value nature of the Mothae kimberlite resource, which is located within 5 km of Letseng, the world’s highest US$ per carat kimberlite diamond mine.

“We are delighted to have recovered our first +100 carat stone so early in our commercial mining

campaign at Mothae, along with other rare Type IIa and fancy coloured gems, and look forward to

unlocking the true value of this mine over the next decade and beyond,” Wetherall concluded.

RapNet to Vote on Synthetics

RAPAPORT PRESS RELEASE, May 22, 2019, Las Vegas … RapNet, the world’s largest diamond trading network with daily listings of over $7.4 billion, will be voting on whether it should provide diamond listing and pricing services for synthetic diamonds. Voting will be limited to registered RapNet members who log in to RapNet.com and will take place from Sunday May 26 through Friday May 31, 2019. The results of the vote will be announced at the Rapaport Breakfast on Sunday June 2, 2019, at the JCK jewelry show in Las Vegas, Nevada. The keynote address at the breakfast entitled “Synthetic Ethics” will be presented by Martin Rapaport. The Rapaport Breakfast is open to the jewelry trade and media. Registration and information is available here. The breakfast and additional Rapaport “Ethical Sourcing” and “Appraiser” Town Hall Meetings will be broadcast live on Facebook here. The issue of synthetic diamonds is hotly debated in the diamond and jewelry trade. Recent decisions by the US Federal Trade Commission (FTC) have removed the word natural from the definition of a diamond. The FTC believes that diamonds need not be natural to be described as diamonds, although they require disclosure when a diamond is “man-made” or “laboratory-created.” Martin Rapaport has published an important article about the issue entitled “Synthetic Ethics” that can be reviewed here. The vote will provide RapNet and the jewelry industry with important input as to the role of synthetic diamonds in the diamond trade. The final decision regarding the matter will be made by the RapNet management team. “Synthetic diamonds present significant challenges and opportunities to the diamond trade. The role of natural diamonds is threatened as synthetic diamonds offer consumers lower prices and provide retailers with higher profit margins. The problem with synthetic diamonds is that they are not a store of value as they have no natural scarcity and can be manufactured with unlimited supply. Their prices are expected to decline over the long term as their cost of manufacturing falls. The diamond trade must decide if they want to trade in long-term integrity for short-term profits,” said Martin Rapaport, Chairman of the Rapaport Group. About the Rapaport Group: The Rapaport Group is a global provider of added value services that support the development of ethical, transparent, competitive and efficient diamond and jewelry markets. Established in 1978, the Rapaport Price List is the primary source of diamond price and market information.

SEC Cracks Down on ICO That Offered Investors Colored Diamonds

The ICO that was promoted as a game-changer on the diamond market faces a dramatic fall from grace.

The U.S. Securities and Exchange Commission (SEC) has pulled the plug on a $30 mln cryptocurrency Ponzi scheme called Argyle Coin. The company, which promised to turn fancy colored diamonds into globally accessible assets, defrauded more than 300 investors.

No diamonds for you

Who told you that colored diamonds are only for ultra-rich individuals? Argyle Coin allowed the average Joe to invest in one of the rarest diamonds in the world. The project was presented as a Blockchain-powered marketplace for trading these precious rocks.

According to the SEC’s press release, Argyle Coin was nothing more than a Ponzi scheme that defrauded new investors in order to pay returns to the old ones. On top of that, Jose Angel Aman, the man behind this scam, used investors’ funds in order to enrich himself (he bought real estate and horses). Overall, those who wanted a piece of luxury ended up losing $10 mln.

As alleged, Aman operated a complicated web of fraudulent companies in an effort to continually loot retail investors and perpetuate the Ponzi schemes as well as divert money to himself,” said Eric I. Bustillo, Director of the SEC’s Miami Regional Office.

Old story, new names

Argyle Coin was supposed to offer its clients a ‘risk-free’ investment opportunity given the ICO is backed by over $25 mln of fancy colored diamonds that are securely stored in the London-based Malca-Amit vault.

Notably, prior to Argyle Coin, Aman had managed to pull off two similar scams – Natural Diamonds and Eagle. Aman was charged with violating securities law antifraud provisions.

GIA Spots Natural-Synthetic Hybrid Diamond

The Gemological Institute of America (GIA) has discovered a synthetic layer that improved the weight and color of a natural diamond, and has warned that the phenomenon may be happening more often.

The cushion modified brilliant, 0.64-carat stone contained about 0.10 carats of chemical vapor deposition (CVD) diamond, the GIA estimated in a lab note last week. The lab-grown layer was greyish-blue, in contrast to the natural section’s yellowish color, giving the combined stone a fancy-greyish-greenish-blue appearance.

This was not the first time a stone of this type has turned up at the GIA: In 2017, it reported on a 0.33-carat, fancy-blue diamond that featured a CVD overgrowth similar to this one.

“With the second of these composites seen at GIA, this could be a new type of product entering the market,” research associate Troy Ardon and analytics technician Garrett McElhenny wrote in the note, which the GIA published in the Spring 2019 issue of its quarterly scientific journal, Gems & Gemology. “The resulting color was likely the main motivation for growing the CVD layer on top of the natural diamond, though the extra weight gained could also be a factor.”

The stone’s unusual nature came to light after testing indicated it had features of both type Ia and type IIb diamonds — a rare combination. It appeared to have absorbed both nitrogen — a feature of type Ia diamonds that gives yellow color — and boron, which is present in type IIb stones and can turn them blue. “Mixed-type diamonds always call for additional scrutiny,” Ardon and McElhenny explained.

The pavilion — the section from the girdle to the bottom — showed natural growth features during fluorescence testing with DiamondView, a De Beers machine for identifying synthetics. However, the crown displayed characteristics of CVD, proving that manufacturers had grown CVD diamond over a natural base. Using computer modeling, the research team was able to calculate the weight of the synthetic part as approximately one-tenth of a carat.

The stone was well disguised: Numerous readings of its photoluminescence showed no indication of any synthetic origin, despite the fact that such tests are usually effective at revealing CVD. This may be because the lab-grown layer was so thin, the note pointed out.

“Natural diamonds with synthetic diamond grown on the surface require extra scrutiny due to the presence of natural-looking features, both spectroscopic and gemological,” the authors continued. “Careful inspection still reveals the presence of synthetic indicators, which expose the true nature of the diamond.”
