GIA Spots Rare Inscription Fraud in Simulant

The Gemological Institute of America (GIA) has uncovered three synthetic moissanites with forged inscriptions that fraudsters had used to misrepresent them as natural diamonds.

The cases at the Johannesburg laboratory marked the first times the GIA had discovered fake girdle inscriptions on diamond simulants, it said in a recent article in its academic journal, Gems & Gemology.

The lab initially received a round brilliant, 1.02-carat stone for a diamond-grading report. The report number on the girdle was for an E-color natural diamond with the same weight that was graded in 2019, but the dimensions were different because moissanite has lower specific gravity, meaning that it weighs less relative to its volume.

Standard testing showed the stone was not a diamond, while subsequent spectroscopic and gemological analysis proved it was synthetic moissanite, GIA researchers wrote in the fall 2020 edition of Gems & Gemology, which it released last week.

“The possibility exists that a consumer could purchase this simulant thinking it was a natural diamond, especially with a deliberately misleading inscription,” wrote Sicebiso Hlatshwayo, a supervisor of diamond grading at the GIA in Johannesburg, and Sally Eaton-Magaña, senior manager of diamond identification at the GIA in Carlsbad, California.

Since writing the article about the first stone, the same lab in South Africa received and identified two more synthetic moissanites with fraudulent inscriptions, the GIA added in a note.

In addition to the size discrepancy, the first stone’s clarity was equivalent to VVS2 (the GIA doesn’t usually give moissanite a grade of this type), whereas the diamond it was impersonating was VVS1. The inscription’s font was also distinctly different from the GIA’s standard one. The GIA obscured the fraudulent inscription, in line with its usual practice.

People sometimes mistake synthetic moissanite for diamond because some of their properties are similar, such as their hardness and thermal conductivity, the gemologists explained. The latter feature is often a method of distinguishing diamonds from simulant, but it can fail if the stone is moissanite.

However, the stone showed “double refraction” — a feature of moissanite, absent in diamonds, that gives it more brilliance.

Another key difference between the materials is dispersion, the GIA pointed out. Moissanite has higher dispersion, meaning light that enters the stone is refracted more. The eye, therefore, sees a more distinct range of colors, giving it more “fire” than diamonds.

Mountain Province’s first diamond sale of 2021 shows 8% price rise

After a devastating 2020 which saw a near-collapse in the global diamond trade, Mountain Province Diamonds‘ latest sales figures show the sparkle may be starting to return to the diamond sector.

The 49% owner of the Gahcho Kué mine in the Northwest Territories, operated by 51% owner De Beers, sold 241,827 carats of diamonds for $21.8 million or $90 per carat in the sale, which closed on Jan. 22 in Antwerp. That represents an encouraging increase from an average sales price of $64 per carat in the final quarter of 2020 and $37 per carat in the third quarter.

“The first sale of the year was excellent, the growing confidence amongst rough diamond buyers translated into a healthy price improvement of 8% on a like for like basis when compared to our record high volume December sale,” said Mountain Province president and CEO, Stuart Brown, in a release. “We expect to see a continuation of the positive trend as rough and polished markets continue to strengthen post a successful retail season.”

The company’s next sale, in February, will include the 157-carat “Polaris” gem diamond, recovered in the fourth quarter. Named after the North Star, the stone appears colourless in daylight, but under ultraviolet light “exhibits a rare natural blue fluorescence that echoes its Arctic origins.”

Mountain Province recently released its production and sales results for the fourth quarter. Two confirmed cases of covid-19 during the quarter affected production as existing health and safety precautions were further enhanced. For the quarter, the operation saw a 12% decrease in total tonnes mined (ore and waste), a 21% decrease in tonnes treated (to 736,140 tonnes), and a 23% decline in carats recovered (to 1.5 million carats).

Mountain Province’s share of fourth-quarter production was nearly 745,600 carats.

For the year, the company recorded total sales of 3.3 million diamonds at an average price of $51 per carat for C$227 million ($171.3 million) in revenue.

“Under very difficult circumstances, all driven by Covid-19, the Gahcho Kué mine has performed well in being able to maintain production, albeit at a reduced level, and came very close to the revised guidance in tonnes mined and treated and exceeded the revised guidance target for carats recovered,” Brown said earlier this month on the release of the production figures. He added that the carat recovery was “particularly pleasing under the circumstances” and positioned the company for positive sales numbers in the first quarter of 2021.

Brown said that the last quarter of the year saw a “strong recovery” in the diamond market. In addition, the late 2020 closure of Rio Tinto‘s high-volume Argyle mine in Australia is expected to help establish a “more balanced” supply and demand equilibrium.

“The diamond market came under unprecedented pressure from early March to early September and although this pressure remains, we did see a strong recovery with respect to rough diamond demand in the last quarter of the year,” Brown said. “The two sales during the last quarter saw significant price recovery across all categories of diamonds sold. Early diamond jewelry retail sales reports are encouraging, and we expect to see steady demand for rough diamonds in the first quarter of 2021. There will no doubt still be challenges ahead but we are certainly more positive in our outlook as we start 2021 compared to the middle of 2020.”

Bristow to finally put Rockwell Diamonds saga to bed after firm unveils wind-up plan

MARK Bristow, CEO of Barrick Gold Corporation, is to finally close the book on Rockwell Diamonds, a company he chaired and which he once attempted to save from bankruptcy.

Rockwell Diamonds announced today the Canadian listing authority had revoked a cease trade order which had been issued as the company had previously failed to produce quarterly numbers with the accompanying management discussion.

The company today filed third quarter numbers and announced its intention to wind up its affairs in which a company owned by Bristow, ‘Bristco’ would mop up the interests of minority shareholders in Rockwell and put them into ‘Amalco’.

Dissenting shareholders would have their interests exchanged on a one-for-one basis for redeemable preference shares of Amalco.

The redeemable preference shares would then be immediately redeemed by Amalco in exchange for half a Canadian cent per share, payable in cash. A meeting of shareholders requiring a simple majority has been arranged for March 2.

Bristow first sought to bail out Rockwell Diamonds, which was once run by his brother, John Bristow, in 2014, in which Mark Bristow bought $1.1m in debentures. In 2016, Bristow embarked on a process of ‘fumigation’ in which he restructured the firm’s board and conducted an overview of its operating activities.

Unfortunately, the company never managed to gain traction at its key asset, the 200,000 cubic metres a month Wouterspan, situated in the alluvial diamond fields region of the Northern Cape province.

There was a proposed $8m recapitalisation of the company in 2017.

The company was subsequently put into liquidation proceedings following attempts by a business practitioner to save it from failure. The company was in and out of court throughout this period with claims of corruption involving contractors.

In 2019, Bristow completed the merger of his Randgold Resources with Barrick Gold, a fabulously successful transaction which as coincided with high gold prices.

De Beers and Alrosa Raise Rough Prices

The two largest diamond miners increased prices at this week’s rough sales as demand improved due to post-holiday restocking and strong trading ahead of the Chinese New Year.

De Beers raised prices by an average of 4% to 5% at its first sight of 2021, while Alrosa’s increases were around 6% to 7%, industry insiders told Rapaport News Monday. Both companies implemented steeper hikes in larger categories than for smaller goods, sources said.

“Alrosa makes sure that prices reflect the actual market trends and a confirmed real demand,” a spokesperson for the Russian miner said. De Beers declined to comment.

The miners have steadily been reversing the prices cuts they made in the second half of last year. De Beers’ price rise was its second in a row, with January prices almost back to pre-pandemic levels, sightholders noted.

The rough market showed momentum in January following a better 2020 holiday season than many had feared earlier in the year. Cutting factories in India raised polished production to full capacity as shortages emerged and retailers restocked, prompting manufacturers to buy rough in large quantities.

Demand rose on the secondary market, with De Beers clients able to make profits of 5% to 7% by reselling goods ahead of the sight. Those premiums declined slightly following the price increase.

“[Polished] inventory levels are the lowest for at least the past seven or eight years,” an executive at a sightholder said. “That’s the reason people are going to be more aggressive in their purchasing,” he continued, adding that some traders foresaw a spike in consumer demand due to government stimulus packages.

Prices at smaller miners’ tenders were higher still — in contrast to mid-2020, when manufacturers could get goods up to 25% cheaper on the open market compared with De Beers and Alrosa boxes. Tender prices fluctuate with the market conditions more than contract-sale prices do, as the smaller rough producers have greater liquidity needs.

Some traders expressed concern that the surge in rough purchases could lead to an oversupply, as Chinese retailers have almost finished preparing their inventories for the upcoming lunar festival on February 12.

“It’s time to go back to business, but it’s no time to push your production to the max and buy rough at any price with the excuse that your factory needs it,” another sightholder argued. “The end of year has been OK, including in the States. There are great expectations for a fantastic Chinese New Year, but the reality is that any Chinese retailer has stopped buying as from this week.”

Amid the uncertainty, Alrosa kept its policy of allowing customers to defer 100% of their allocations in January, noting that it wished to uphold the balance between supply and demand.

De Beers also allowed sightholders to refuse a proportion of their allocations for goods up to around 0.75 carats, while maintaining its standard flexibility — including 10% buybacks — in larger categories.

De Beers’ sight began on Monday in Botswana and runs until Friday, with viewings also taking place in Antwerp and Dubai. Alrosa’s sale started last Friday and continues for a week.

Lucapa’s run of recovering +100 carat diamonds continues

Lucapa Diamond Company and its partners have announced the recovery of the 18^th +100 carat white diamond by Sociedade Mineria Do Lulo (SML) from its Lulo alluvial mine in Angola.

The recovery of this second +100 carat diamond from Mining Block 46 (MB46), a 104 carat D colour white stone, so soon after the 113 carat D colour white stone, indicates the potential for these blocks as the company moves deeper into the southern terraces.

Lucara recovers 341 carat white diamond

341 carat white diamond found at the Karowe mine in Botswana

Canada’s Lucara Diamond has found an unbroken 341-carat white gem-quality rock at its prolific Karowe mine in Botswana, with analysts estimating it could fetch more than $10 million.

The Vancouver based miner said the diamond was recovered over the Christmas period from milling of ore coming from the south western quadrant of Karowe’s South Lobe.

The diamond is the 54th stone over 200 carats recovered at Karowe since it began commercial operations in 2012.

The find builds on previous historic recoveries which include the 342-carat Queen of the Kalahari, the 549 carat Sethunya, the 1,109 carat Lesedi La Rona found in 2015, and the 1758 carat Sewelô, recovered in 2019.

Beyond Sewelô, the only larger diamond ever unearthed is the 3,106 carat Cullinan Diamond, discovered in South Africa in 1905. The Cullinan was later cut into smaller stones, some of which now form part of British royal family’s crown jewels.

Petra Diamonds’ investors back restructuring

Petra Diamond’s Finsch mine in South Africa

Struggling Petra Diamonds (LON: PDL) said on Wednesday its investors have approved plans to restructure the business, a move that aims to provide the miner with a more stable, deleveraged capital structure to ensure its short and long-term viability.

Over 95% of shareholders voted in favour of a resolution that includes reducing authorized share capital of the company by cutting the nominal value of all ordinary shares from 10p to 0.001p.

SIGN UP FOR THE PRECIOUS METALS DIGEST
It also involves an increase to Petra’s authorized share capital through the creation of 8.5-million ordinary shares and the authorization for directors to allot ordinary shares up to £88,447 ( just over 8.8-million ordinary shares).

Hefty debt
Petra Diamonds’ weak financial position, a product of stagnant demand and heavy borrowing to expand its mines, particularly the iconic Cullinan, pushed it to put itself up for sale in June. Petra reversed the decision in October, opting instead for the debt-for-equity restructuring approved Wednesday.

The company noted it expected to complete the reorganization in the first quarter of 2021.

Petra’s shares slumped by more than 80% last year as the covid-19 pandemic battered the global diamond sector, with mines forced to shut down while consumer demand continued to fall.

The diamond miner, which has three operations in South Africa and one in Tanzania, is also dealing with allegations of human rights abuses at its Williamson mine in Tanzania, resulting from the actions of its security guards.

Mothae diamonds sell for $7.2 million

Lucapa Diamond Company and its partner, the Government of the Kingdom of Lesotho, have provided an update on the first sale of diamonds in 2021 from the Mothae kimberlite mine in Lesotho.

The parcel of 4,676 carats of rough diamonds were sold for a total of US$5.6 million or US$1,198 per carat. This is the highest average US$ per carat price achieved by Mothae on the sale of any run of mine production parcel.

The sale included a number of Specials (diamonds weighing >10.8 carats), including the 101 carat D colour diamond recovered following re-opening of the mine in Q4 2020, which is the most valuable diamond recovered to date at Mothae.

Lucapa MD, Stephen Wetherall comments:

“Following a tough 2020, where both of our mines were impacted by the pandemic, our valued teams have shown their resilience and operations have bounced back strongly.

“The good recoveries at both mines and growing demand leading to strengthening diamond prices has seen a strong start to 2021.”

“We look forward to Mothae receiving further value following implementation of the cutting and polishing partnership and to completing the expansion at Mothae this quarter.”

Tiffany to Sell Its Most Expensive Diamond

Tiffany & Co. will offer a necklace featuring an 80-carat diamond, expected to be its most expensive piece ever, at the reopening of its New York Fifth Avenue flagship store next year.

The oval-cut, D-color, internally flawless stone, which the jeweler sourced from Botswana and will set in-house in New York, is at the center of the piece, Tiffany said Tuesday. It is also the largest diamond the company has ever offered. Only the 128.54-carat, yellow Tiffany Diamond worn by both Audrey Hepburn and Lady Gaga is larger, and that piece is not for sale.

*The original 1939 version of the necklace*

The jewel is a reimagined version of a Tiffany necklace created in 1939 for the World’s Fair, which features an aquamarine in place of the diamond. The unveiling of that piece set the stage for the original opening of the flagship store on the corner of 57th Street and Fifth Avenue in 1940.

“What better way to mark the opening of our transformed Tiffany flagship store in 2022 than to reimagine this incredible necklace from the 1939 World’s Fair, one of our most celebrated pieces when we opened our doors…for the first time,” said Victoria Reynolds, chief gemologist at Tiffany.

Diamond Prices Firm After Supply Declines

Diamond trading was seasonally slow in December as the industry’s focus shifted to retail and as diamantaires took their end-of-year break. Sentiment received a boost from strong holiday e-commerce sales, the distribution of Covid-19 vaccines, and the US approval of a $900 billion coronavirus stimulus package.

Polished prices firmed as supply declined due to limitations on diamond manufacturing during India’s lockdowns. The RapNet Diamond Index (RAPI™) for 1-carat diamonds rose 2.3% in December and 5.8% for the full year.

RapNet Diamond Index (RAPI™)
	December	4Q 2020	FY 2020
RAPI 0.30 ct.	0.4%	-4.7%	0.2%
RAPI 0.50 ct.	0.8%	-2.3%	12.1%
RAPI 1 ct.	2.3%	3.8%	5.8%
RAPI 3 ct.	2.5%	7.0%	3.7%

The industry began 2021 with a healthier supply-demand balance than it had at any stage in the past five years.

The volume of 1-carat diamonds on RapNet in the D-H, IF-VS range — the categories the RAPI measures — declined 24% in the second half of 2020. The top 10% of diamonds in that category were selling at an average of 32% below the Rapaport Price List on January 1, 2021, compared to 37% below on July 1, 2020. The lower discount suggests that demand is stronger relative to the available supply.

Manufacturers are raising polished production in anticipation of steady first-quarter orders as jewelers and dealers seek to replace inventory they’ve sold during the holiday period.

Jewelers with solid e-commerce programs had a good season. Many off-mall independents also did well, as consumers felt safer visiting stand-alone stores than crowded malls and were driven to support local community businesses following the Covid-19 lockdowns. Independents without an effective online presence struggled.

US jewelry sales for October 11 to December 24 fell 4.3% year on year, according to Mastercard SpendingPulse. Online jewelry sales grew 45%.

There is some optimism for the year ahead even as Covid-19 continues to disrupt business activity. To ensure growth, the trade must intensify its efforts to engage with consumers via storytelling and improved omni-channel platforms while keeping supply in sync with prevailing levels of demand.
