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



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.”

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.
