Alrosa to Sell Directly to Consumers

Alrosa is launching a source-of-origin program that will enable dealers and consumers to buy polished diamonds with detailed provenance information.

The Russian miner will create an “electronic passport” for each diamond on a new website, diamonds.alrosa.ru, presenting the stone’s physical characteristics, age, and place and date of extraction, as well as where and when it was cut. It will also name — and provide some information on — the artisan who polished the stone. The story will be viewable as an automated video.

The platform is initially aimed at the trade, but the company will open it up to the public in the fall of this year, it revealed last week during the JCK Las Vegas show.

“As part of the platform, there will be an option for end consumers to buy diamonds directly from Alrosa — for those individuals who want to buy a diamond with a provenance,” a spokesperson for the miner confirmed to Rapaport News Tuesday.

Proof of origin has gained importance for diamond miners, with De Beers launching a provenance program in April that enables consumers to view sustainability credentials for its mines at dtc.com. Alrosa explained its strategy during the JCK show, arguing that it was taking the issue much more seriously than many other market players.

“The traceability of a diamond is a pledge of confidence to anyone making such a purchase,” Alrosa added. Information on provenance, social responsibility and a stone’s non-conflict status “are all required by purchasers, especially younger generations,” the company noted. It’s currently trialing the system with 2,000 diamonds, and plans to increase that number soon.

Alrosa’s program will encompass diamonds from its own polished division, which had sales of approximately $95 million in 2018. The company is in negotiations to acquire Russian manufacturer Kristall, which would triple its polished output. The deal is expected to close this year, company representatives said.

Lucapa diamonds sell for $14.5 million at auction

Lucapa Diamond Company has continued its successful run at auction after securing $US10 million ($14.5 million) for the sale of alluvial diamonds from its Lulo mine in Angola, central Africa.

The run-of-mine diamonds, which totalled 5573 carats in weight (around 11.15 kilograms), achieved an average price of $US1800 a carat.

Several more high-value Lulo diamonds — including a 130-carat type IIa diamond and 45-carat pink — are still being held as inventory by partner Sociedade Mineira Do Lulo (SML), which is operated and 40 per cent-owned by Lucapa.

SML plans to expand Lulo’s plant throughput by 50 per cent to around 450,000 bulk cubic metres by 2020. The company upgraded Lulo’s JORC resource in January by 90 per cent to 80,400 in-situ carats at an average price of $US1420 a carat.

It is Western Australia-based Lucapa’s fourth diamond tender in 2019, following two auctions in February and a third in May.

It is also the second tender of the year from the company’s Lulo mine. The first auction, which took place via electronic tender in Luanda, Angola in February, remains the company’s largest sale of the year so far. It secured $US16.7 million for the sale of seven large diamonds at an average price of $US33,530 a carat.

The other two auctions related to the sale of diamonds from Lucapa’s other African mine, the Mothae kimberlite joint venture project between Lucapa (70 per cent) and the Government of the Kingdom of Lesotho in southern Africa (30 per cent).

These sales took place in Antwerp, Belgium in February and May, and raised $5.3 million and $US3.5 million respectively.

Lucapa launched commercial production of Mothae in January this year. The company is also progressing two early-stage exploration projects: Orapa Area F in Botswana and Brooking in Western Australia.

RapNet Members Say ‘No’ to Synthetics

The RapNet community has voted overwhelmingly against introducing services for the lab-grown-diamond sector.

Members voted by 79% to 21% against the trading platform listing synthetics on the site. They also rejected a lab-grown price list, with 74% voting “no.”

The poll took place on RapNet last week. The audience applauded when Martin Rapaport, Chairman of the Rapaport Group, revealed the results Sunday at the annual Rapaport Breakfast at JCK Las Vegas.

Following the results, RapNet will not provide a trading platform for synthetics, or introduce a price list for the product, Rapaport confirmed. “We believe the current prices for synthetic diamonds are artificial, as they are based on misleading disclosure,” he added.

Voters also heavily backed the view that synthetics producers must disclose post-growth treatments, and supported the establishment of an organization for the natural-diamond industry.

RapNet vote results:

Should RapNet list synthetic diamonds?
Yes: 1,607 (21%)
No: 5,934 (79%)

Should Rapaport publish a synthetic price list?
Yes: 1,885 (26%)
No: 5,232 (74%)

Should synthetic diamonds be required to disclose treatments?
Yes: 5,892 (88%)
No: 819 (12%)

Would you support establishment of a natural-diamond organization?
Yes: 5,528 (85%)
No: 1,104 (15%)

Nirav Modi Assets Set for Vegas Auction

A selection of jewelry and intellectual property belonging to Nirav Modi’s Firestar Diamond and Fantasy businesses will be up for auction at the JCK Las Vegas show.

The sale will feature $3.5 million worth of Nirav Modi jewelry, including wedding bands, bracelets and necklaces. Purchasers will also be granted the patents to reproduce the jewelry in the US and other countries, according to the Gem Certification and Assurance Lab (GCAL), which is organizing the event.

Firestar’s liquidators have already auctioned several of the lots from Modi’s US companies, including the trademark rights to “Diamonds Are a Girl’s Best Friend,” which was purchased for $50,000 in October.

The sale will take place on June 7 at GCAL’s JCK booth. It is the eighth in a series of sales of Modi’s US assets. The Indian jeweler, who allegedly defrauded Punjab National Bank of $2 billion, was arrested in London in March.

Rough diamonds from Mothae fetch US$3.5 million in Antwerp

Lucapa Diamond Company and the Government of Lesotho have announced results from the second tender in 2019 of diamonds from the new Mothae kimberlite mine in Lesotho.

The parcel of 7,008 carats of rough diamonds sold at tender in Antwerp for a total of US$3.5 million.

The tender included prices of up to US$26,000 per carat paid for individual Mothae gems.

Lucapa MD, Stephen Wetherall, says the latest tender results continued to underline Mothae’s status as one of a select few global mines capable of producing high-value diamonds on a consistent basis.

“We continue to be encouraged by the regular recovery of Specials and sales results achieved from the supposed lower-margin areas of the Mothae kimberlite pipe,” says Wetherall.

“These results add to the excitement as our mining campaign prepares to transition to the higher margin diamond zones in the main southern pit in H2 once the water is transferred to our main dam to ensure we have appropriate water supplies for our planned increased treatment rates during the dry months.”

The latest result brings to US$7.3 million the total sale proceeds generated from the two tenders of Mothae diamonds completed this year.

This represents an average overall price of US$588 per carat for the run of mine production and US$729 per carat for diamonds in the +11 sieve
size fraction.

Lucapa is considering a third tender in H1, 2019 following the continued strong recoveries from the new 1.1 Mtpa kimberlite plant, including the 126 carat gem-quality diamond recovered earlier this month and other Type IIa Specials.

As set out in the ASX announcement of 27 May 2019, mining has been restricted predominantly to the lower-margin diamond zones since commercial production commenced at Mothae in January

This due to the decision to delay the scheduled dewatering of the main southern pit to preserve water required to enable the plant to operate at higher throughput rates in H2 2019.

The water in the southern pit will be transferred to the main 500,000 m3 water dam in H2, 2019 when the dam wall is completed.

This will in turn enable Mothae to access the higher-margin diamond zones in the southern pit.

Undisclosed Green Synthetics Raise GIA Eyebrows

Twenty five undisclosed lab grown diamonds have turned up at the Gemological Institute of America (GIA) including several with a rare greenish color.

The GIA’s lab in Carlsbad, California, recently received the stones weighing from 0.46 to 0.52 carats for grading reports. They all proved to have been created using High Pressure High Temperature (HPHT), GIA senior research scientist Sally Eaton Magaña explained in a lab note published in the Spring 2019 issue of Gems & Gemology, the institute’s quarterly scientific journal.

While nine of the stones were colorless or near-colorless, eight had faint yellow green color, seven were faint green, and one was very light green. The coloring resulted from a high concentration of nickel, an impurity that’s common in HPHT, but rarely in large enough amounts to affect the color, Eaton Magaña explained. (In diamonds at large, nickel can cause a green hue.) GIA gemologists previously reported on a fancy deep yellowish green HPHT diamond in 2017, with nickel also the cause in that case.

“As laboratory grown diamond manufacturers continue to experiment with their recipes and the process further evolves, we will likely see greater quantities and a wider variety of color ranges,” Eaton Magaña wrote. The occasion also gave a rare opportunity to analyze a large dataset of similar but unusually colored HPHT diamonds, she noted.

The Spring edition of Gems & Gemology also reported on a natural diamond with a synthetic layer the second such case the GIA had seen in about two years.

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

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.

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.
