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. 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.”

Monica Bellucci Wore the Historic Cartier María Félix Tribute Necklace at Cannes

There are a select few necklaces that might be deemed jewelry royalty Marie Louise’s diamonds from Napoleon, the Maharajah of Patiala’s bib, Daisy Fellowes’s Tutti Frutti, the Duchess of Windsor’s Zip, and of course, the one made by Cartier in 1975 to resemble two fully articulated crocodiles and using 1,023 yellow diamonds, 1,060 emeralds, and two cabochon rubies for Mexican actress María Félix.

Félix’s necklace was based on her own pet croc she even brought it into the store to make sure Cartier got it just right. She even suggested they live there for a while, just in case. Only one person other than María Félix has ever worn that necklace, now owned by the Cartier Collection.

In 2006, actress Monica Bellucci paired the necklace with a crisp white shirt for the red carpet at Cannes.

Over the weekend, on that same red carpet, Bellucci wore Cartier’s one of a kind diamond and emerald necklace made in tribute to the iconic piece and created by the same artisanal sculptor who brought María Félix’s little pets to life.

The María Félix Tribute necklace is in all diamonds and emeralds totaling 46.45 carats, and is by all reports “strikingly realistic with a body and legs ready to move!”

The crocodile necklace is of course but one proud member of the Cartier menagerie. The Panther, brought to three dimensional life in 1948 for the Duchess of Windsor, being the most iconic.

To make sure those diamond and onyx figures looked ready to pounce, legendary Cartier jewelry Director Jeanne Toussaint made all her designers spend quality time at the Paris zoo.

Russia’s major diamond mining firms including Alrosa have urged India to amend consumer laws on synthetic diamonds so that there is clarity on the quantity of synthetic diamonds entering the country and how they are being used.

Industry executives said that around 5 million carats of synthetic diamonds are produced globally, and the volume is increasing, causing concern to rough diamond producers. A senior executive, who did not wish to be identified, told the Economic Times that a meeting was recently held between India and Russia on synthetic diamonds.

“India is the chair of the Kimberley Process Certification System (KPCS) for 2019 and the Russian Federation is the vice chair. The KPCS is a joint initiative of 54 members, including India and the European Union, to stem the flow of ‘conflict diamonds’ that are used by rebel groups to overthrow legitimate governments.

It came into effect on January 1, 2003 through a United Nations General Assembly Resolution and includes governments, civil society and industry.”

“During the meeting between Aleksey Vladimirovich Moiseev, the KPCS vice chair 2019 and deputy minister of finance of the Russian Federation Peter Karakchiev, Alrosa’s head of international relations department and other senior representatives of the Russian foreign office it was decided that the KPCS should work towards having separate HS (harmonized system) code implemented for synthetic rough diamonds at the national level and encourage participant countries to expedite the process of implementation.

118ct. Yellow Smashes Estimate at Christie’s

A diamond bought in memory of late diamantaire Sam Abram sold for more than double its high estimate at Christie’s Geneva auction Wednesday.

The cushion brilliant-cut, 118.05-carat, fancy-yellow, VS2-clarity stone fetched $7.1 million, or $60,000 per carat, at the Magnificent Jewels auction. The diamond, which was estimated at $2.5 million to $3.5 million, was purchased by Siba Corp. in honor of its former president. The company subsequently named it The Siba Diamond.

Three ruby pieces broke the top 10, all selling for well above their estimates. A 22.86-carat Burmese ruby ring by Harry Winston went for $7.2 million against its high estimate of $3 million, a final price of $314,900 per carat. Meanwhile, a Van Cleef & Arpels ruby and diamond necklace, which was valued at $400,000 to $600,000, garnered $2.4 million, and a ruby and diamond bracelet by the same jeweler fetched $1.6 million. That piece was estimated at $150,000 to $250,000.

A necklace comprising 110 natural pearls achieved $5.8 million, well above its high estimate of $3.5 million. All other pearl pieces of note offered at the sale also exceeded their original estimates, Christie’s said.

Other notable lots included a pear-shaped, 75.61-carat emerald pendant necklace that belonged to the Grand Duchess Vladimir of Russia, which sold for $4.3 million, or $57,300 per carat. It was estimated at $2.3 million to $3.5 million.

“Natural pearls and jewels with noble provenance, such as the 75.61-carat emerald from Grand Duchess Vladimir of Russia, found much acclaim and sold for far above their presale estimates,” said Rahul Kadakia, Christie’s international head of jewelry. “Also of note was the 118-carat, fancy-yellow diamond that was purchased by Siba Corp. in honor of Sam Abram, a prominent figure in the jewelry world, who very sadly passed away last week.”

In addition, the rectangular-cut, 25.27-carat, D-color Jonker V diamond connected to Anglo American founder and former De Beers chairman Sir Ernest Oppenheimer fetched $3 million against a valuation of $2.5 million to $3.5 million.

Christie’s sold 87% of all lots on offer, it said. The sale brought in a combined $62.1 million.

Debmarine Namibia invests in custom diamond vessel

The vessel, which has an expected total capital cost of US$468 million, will be the seventh in Debmarine’s fleet. It is expected to start production in 2022 with the capacity to add 500,000 carats of annual production, a 35% increase above current levels.

De Beers CEO Bruce Cleaver said some of the highest quality diamonds in the world were found at sea off the Namibian coast.

“With this investment we will be able to optimise new technology to find and recover diamonds more efficiently and meet growing consumer demand across the globe,” he said.

Anglo American CEO Mark Cutifani said the addition of the vessel would bring numerous benefits, including improving De Beers’ production profile by value and volume, greater efficient and productivity through the vessel’s deployed technologies, and sustained economic benefits for Namibia.

“This highly attractive investment offers a three-year payback, a more than 25% IRR and an EBITDA margin of more than 60% – typical of the high quality of our brownfield growth options,” Cutifani said.

“We will continue allocating appropriate levels of capital in a disciplined manner across Anglo American’s wider organic pipeline of near- and medium-term growth opportunities, including the world-class Quellaveco copper development in Peru, that we expect to contribute towards our 20-25% production growth by 2023.”

Debmarine last ordered a new vessel in November 2017. At the time it was projected to cost US$142 million and was expected to start operations in 2021.

130 carat gem quality diamond recovered at Lulo

130 Carat rough diamond from Lulo Angola

The 130 carat diamond is the 13th +100 carat diamond recovered to date and the second recovered so far in 2019.

This recovery, together with the continued recovery of other large special white and fancy coloured diamonds continues to highlight the very special nature of the Lulo diamond concession.

The 130 carat diamond adds to the current inventory of high-value large Special run-of-mine diamonds, including top colour white diamonds, weighing 128 carats and 62 carats, as well as a number of fancy pink coloured diamonds.

The majority of the diamond inventory is scheduled for sale this quarter by the alluvial mining company, Sociedade Mineira Do Lulo, however, some diamonds may be extracted and held for tender at a later date.

Lucapa is a growing diamond company with high-value mines in Angola and Lesotho, along with exploration projects in Angola, Australia and Botswana.

Lucapa’s vision is to become a leading producer of large and premium-quality diamonds – from both alluvial and kimberlite sources – in Africa and other known diamond provinces around the world.

The company’s focus on high-value diamond production is designed to protect cash flows in a sector of the diamond market where demand and prices remain robust.

Lucapa’s flagship asset is the Lulo diamond project in Angola, which is a prolific producer of large and premium-value alluvial diamonds.

Lulo has produced 13 +100ct diamonds to date and is the highest average US$ per carat alluvial diamond production in the world.

Lucapa and its Lulo partners continue to advance their search for the primary kimberlite sources of these exceptional alluvial gems through a systematic drilling and exploration program.

Lucapa commenced commercial diamond recoveries in January 2019 at the company’s second high value mine, the 1.1 Mtpa Mothae kimberlite mine in diamond-rich Lesotho and has already recovered five +50 carat diamonds in its own sampling and commercial mining operations.

Lucapa also has early stage exploration projects at Brooking in Western Australia and Orapa Area F in Botswana.

Lucapa’s Board and managements team have decades of diamond industry experience across the globe with companies including De Beers and Gem Diamonds.

11 Carat Purple Diamond Expected to Fetch Over $10M

Hong Kong based M&B Diamonds expects to sell a record setting purple diamond for more than $10 million, after buying the stone from Alrosa.

The cushion modified brilliant cut, 11.06 carat diamond is the largest fancy deep purple pink stone the Gemological Institute of America (GIA) has examined, according to the August 2018 grading report.

Alrosa originally debuted the gem as part of its “True Colour” collection in September at the Hong Kong Jewellery & Gem Fair. M&B bought it at tender in Moscow about two months ago, Roi Sheinfeld, owner of M&B Diamonds, told Rapaport News Wednesday.

M&B will preview the stone to customers by appointment only at its M&B Private Jewelers retail shops in Hong Kong and Singapore. While Sheinfeld chose not to reveal the stone’s purchase price, he expects the sale to yield more than $10 million, depending on the design.

“As it’s one of a kind…we will exhibit it as [a] polished loose diamond,” Sheinfeld added. “The client who buys it will have the privilege of sitting with our design team and creating a one of a kind bespoke piece.”
