Russia unearths its largest ever colour 236-carat rough diamond

The stunning gem aged from 120 to 230 million years was mined in Arctic Yakutia.

The rough diamond is of deep amber colour, its dimensions are 47x24x22 mm.

The precious discovery was made by workers of remote Ebelyakh mine on river Anabar in the extreme north of Yakutia, not far from shores of Laptev Sea and some 1,211km north west from Yakutsk.

The mine belongs to Diamonds of Anabar, part of ALROSA Group.

The rough diamond is of deep amber colour, its dimensions are 47x24x22 mm.

The decision hasn’t yet been made as to whether it’ll be sent to Alrosa’s in-house cutting and polishing division, or sold rough.

‘Such a large natural color rough diamond is a unique discovery.

‘Now, the stone is at ALROSA’s United Selling Organization being studied and evaluated by our specialists.

‘After that, we will decide whether to give it to our manufacturers for cutting or sell it as a rough.

‘Of course, cutters in any country will be interested in such a diamond, as it has the potential to give several high quality polished diamonds,’ said Pavel Vinikhin, head of ALROSA’s cutting and polishing division.

The Ebelyakh mine has produced several brightly-coloured rough diamonds in the past several years.

In summer 2017 alone a crimson, a pink and an intense yellow stones were found within a month.

July Figures Cast Cloud over US Retail Recovery

The US retail outlook is declining after the country’s economic recovery slowed in July amid a resurgence of coronavirus cases, according to the National Retail Federation (NRF).

“A lack of clarity regarding job outlook and future finances tends to influence spending behavior,” said NRF chief economist Jack Kleinhenz. “Coupled with that, uncertainty about further fiscal support from Congress is likely to cause consumers to shift more into saving their money and away from spending.”

The end of supplemental unemployment insurance benefits, which will result in many consumers losing income, could also disrupt retail sales, the NRF said.

While the US Census Bureau has not yet released monthly figures for July, the Federal Reserve Bank of New York’s Weekly Economic Index — a composite of 10 indicators that measure real-time economic activity — fell to -7.24% on July 25 from -6.65% on July 18. Officials at the bank have cited decreased retail sales as the main factor in the drop. The decline comes after US retail sales were up 8% in May compared with the previous month, and rose another 6% in June, NRF data showed.

Meanwhile, The Conference Board’s Consumer Confidence Index, which assesses consumer sentiment, fell to 92.6 in July from 98.3 in June.

“Such uncertainty about the short-term future does not bode well for the recovery, nor for consumer spending,” added Lynn Franco, senior director of economic indicators for The Conference Board.

Jacob & Co Billionaire ASHOKA Watch Features 189 Carats Of Diamonds

It’d take a pretty special kind of bloke to pull this one off. Even among the richest figures currently walking about on this Earth, I just can’t imagine a Bezos, Buffet, or Musk being able to wear the Jacob & Co Billionaire ASHOKA watch on their wrists without every single one of us scrunching up our faces. In any case, it’s very much real and priced at US$7 million.

Reportedly a new and improved update of Floyd Mayweather’s hella frosty 260 carat Jacob & Co Billionaire’s watch – which itself cost US$18 million – this revised iteration features over 189 carats of proprietary diamond cuts by William Goldberg. What’s so special about a William Goldberg ASHOKA diamond? As it so happens, less than 1% of all rough diamonds meet the criteria to even become an ASHOKA. In other words, what you see before you are the elite stones.

With a distinct rectangular shape highlighted by the skeletonised calibre JCAM09 tourbillon movement, this mind-numbingly opulent timepiece is comprised of 167 elements, 19 jewels, and brings a 72-hour power reserve to the table. The 19 jewels themselves have been divided into 62 individual examples to completely cover the case, bracelet, and clasp. But you didn’t need me to tell you where to look for ’em.

Naturally, an offering such as this will be ultra-exclusive. Given the rarity of ASHOKA diamonds in the world, only a single Jacob & Co Billionaire ASHOKA watch will ever be crafted.

Vasana Ratanasunya on her mission to make diamonds everyday jewellery

When Vasana Ratanasunya first set her mind on making VVS & Co. Bangkok a go-to name for every lady looking to enrich their life with a piece of diamond jewellery, she knew she had to take the path less trodden by others in the market in order to achieve her goal.

“There are lot of myths and mindsets when it comes to wearing, and even buying a piece of diamond jewellery,” she said during a dinner meeting with Prestige. “The most important issue, however, is that we measure the value of diamonds by the number of times we can wear them, so the easiest items to sell are some simple piece of earrings or bracelets because people think they can wear them as often as they could. That’s the mindset I want to change.”

A graduate in fashion, Vasana understands the rule of mix-and-match and proportion better than anyone. After her love for fashion has matured into a passion for precious stones that are forever, Vasana brings her own sense of style into bringing diamonds into everyday wardrobe. Her tricks? Go big when you dress down, go moderate when you dress for work, and go big for your evening.

“The problem with women who buy only small items thinking they can wear them often is that, you end up not having a good big piece to wear when you have to attend events like a gala dinner that requires an evening dress. That’s why I always tell people to go for a full matching set of diamond jewelleries instead of buying small pieces here and there. You have this big set for an evening occasion but for everyday, you can just wear a bracelet with your office look, or a pair of chandelier earrings with a t-shirt and denim on a day-out with friends. It’s just about mix-and-match!”

“Most importantly, you invest in this one set and it will become something you can pass on to your children. It has an emotional value that cannot be measured by money.”

Another ground-breaking approach Vasana has brought into the industry is her savviness in social media commerce. With the Covid-19 bringing a slow-down to international export — which previously contributed to the majority of sales for VVS & Co. — Vasana broke out of the crisis using online channels — most notably an Instagram live session which has received huge interests from fans and earned the brand a lot of new customers.

“I would say we are lucky in a way that the name VVS has been in the industry for a long time. People have known about us for decades and they trust our quality. It’s not easy to sell something as expensive as diamonds online. People need to really trust you to buy something this precious from you and we have our history to thank.”

Diamonds Are A Watch’s Best Friend

New models in Harry Winston’s Ocean Biretrograde collection reaffirm the brand’s status as one of the world’s most important purveyors of diamonds. Before the Swatch Group acquired Harry Winston in 2013, it was owned by Dominion Diamond company, the joint venture partner in Canada’s first diamond mine, Ekati, which entitled the company to first pick of run-of-mine gems.

Previous to that, it was owned by the Winston family. It was founded by Harry Winston, whose nickname, “the King of Diamonds,” resulted from his having acquired and sold some of the world’s top diamonds: the 726-carat Jonker; the 94.80-carat Star of the East (which he later sold to the Duchess of Windsor); and the storied 45.52-carat fancy blue Hope Diamond.

The Swatch Group has been careful to honor the legacy of Harry Winston, setting most ladies’ models, and some men’s, with diamonds new pieces in the Ocean Biretrograde Automatic 36mm collection and the more petite Emerald collection.

The Emerald collection is named after the shape of founder Harry Winston’s favorite diamond cut, the emerald. New 18k yellow and white gold models are ideal cocktail watches, at 18mm wide. They come with either a flexible Milanese woven bracelet or a classic satin double tour strap.

And now for the finale of the 2020 lineup: the Precious Cluster, set using Mr. Winston’s signature clustering technique with over seven carats of pear and trillion-cut diamonds, and the Winston Cluster, the high jewelry version with brilliant, marquise, and pear-cut diamonds totaling over 25 carats. The Cluster is a perfect response to the line, “Talk To Me Harry Winston!” from the 1953 song “Diamonds Are A Girl’s Best Friend.”

“Botswana Should Not Produce or Sell Synthetic Diamonds”

According to the official, synthetics will “compromise” the value of Botswana’s natural diamonds

The Letlhakane diamond mine in Botswana — De Beers mining

Masire said that “Botswana will send a confusing message to its customers should it decide to produce and sale synthetic diamonds”. He added that the Debswana Diamond Company (the joint venture between the government of Botswana and diamond miner De Beers) is searching for other markets other than the US to sell its diamonds, including in China.

Masire “refused to provide an update on the ongoing negotiations between Gaborone and De Beers as disclosure of any information pertaining to the negotiations will potentially influence the outcome”. Botswana and De Beers’ huge 10-year diamond sale agreement is expected to expire by the end of 2020. Botswana accounts for more than two-thirds of De Beers’ diamond production.

GIA Embraces Automated Clarity Grading

The Gemological Institute of America (GIA) has teamed up with IBM Research to develop an automated system for grading the clarity of a diamond.

The artificial intelligence (AI) technology uses data from tens of millions of diamonds GIA laboratories have examined in the past, applying the institute’s existing grading standards. It’s already in limited use at the GIA’s New York and Carlsbad laboratories, the institute said Monday.

Grading laboratories have increasingly invested in AI in recent years, as it promises more accurate and consistent results. Sarine Technologies unveiled its automated color and clarity grading equipment in 2016, while the GIA has been working with IBM on the joint project for around two years.

“IBM’s AI technology, combined with GIA’s expertise, extensive data and gemological-research capabilities, enables us to deliver advancements in consistency, accuracy and speed unlike any other organization,” said Tom Moses, the GIA’s executive vice president and chief laboratory and research officer.

The program will initially include the most popular diamond sizes. The GIA aims to expand it to other sizes, shapes and qualities in the future. The GIA and IBM are planning other collaborations combining gemological evaluation with AI.

WA cuts diamond royalty rate

Western Australia has reduced its diamond royalty rate by a significant 33.3 per cent, a move that has been welcomed by Gibb River Diamonds.

The company’s lobbying has led to the reduction of the state diamond gross royalty rate from 7.5 per cent to 5 per cent.

Gibb River stated that the royalty change was in line with the recommendations of the Mineral Royalty Rate Analysis report.

This was published by the Western Australian Department of State Development and Department of Mines and Petroleum in 2015.

“The board of (Gibb River) believes that the reduction of the diamond royalty will have a very positive effect on the sector and is an extremely helpful step in further (Gibb River’s) aim of becoming a profitable diamond producer in Western Australia,” the company stated in an ASX announcement.

The rate is comparable to the 5 per cent royalty rate applied to Rio Tinto’s Argyle diamond project in Western Australia as of May this year, which was amended from the 7.5 per cent rate in 2006 when Rio Tinto decided to proceed with underground mining.

Gibb River operates the Ellendale diamond project in the West Kimberley, which supplies over 50 per cent of the world’s fancy yellow diamonds every year.

The rare colour had driven United States jeweller Tiffany & Co to ink a six-year deal with Ellendale’s former operator, Kimberley Diamonds, for the supply of the diamonds in the past.

Alrosa, ZCDC JV starts prospecting for diamonds in Zimbabwe

Alrosa Zimbabwe (Alrosa Zim), a joint venture (JV) between Russian diamond miner Alrosa and Zimbabwe State-owned miner Zimbabwe Consolidated Diamond Company (ZCDC), has started prospecting and preliminary exploration works for primary diamond deposits.

After getting special grants from the Ministry of Mines and Mining Development, Alrosa Zim had the environmental-impact assessment (EIA) approved by the Environmental Management Agency (EMA), and is set to begin prospecting and exploration in the Masvingo, Matebeleland South and Matebeleland North provinces of Zimbabwe.

In July, Alrosa Zim’s geologists started geochemical sampling, trenching and pitting in Malipati zone, with ground geophysical surveys to follow.

The same prospecting work, including airborne geophysical surveys, is set to be conducted in the Maitengwe area towards the end of year.

Bulk sampling and drilling are set to begin in 2021.

“Following the signing of a JV agreement with ZCDC to develop diamond deposits in Zimbabwe in December 2019, we are progressing well towards the initiation of the full-scale prospecting works this year.

“Being a member of Responsible Jewellery Council, the World Diamond Council and the Natural Diamond Council, Alrosa complies in full with all industry commitments on responsible business practices and its own corporate standards.

“Alrosa is committed to follow these principles strictly while working in Zimbabwe, minimising adverse environmental impact in all areas of activities and using mineral resources comprehensively and rationally,” says Alrosa deputy CEO Vladimir Marchenko.

Alrosa expects to investment $12-million in Zimbabwe from 2020 to 2022.

Alrosa holds 70% of Alrosa Zimbabwe, and ZCDC the balance. The JV focuses on prospecting, exploration and mining of primary diamond deposits in Zimbabwe.

Petra Diamonds sells Botswana exploration assets

Petra Diamonds (PDL.L) has agreed to sell its Botswanan exploration assets to Botswana Diamonds (BODP.L) for $300,000 and a 5% royalty on future revenue, the diamond miner, which is in the process of restructuring, said on Monday.

The purchase price will be payable in two equal instalments on or before August 31, 2021 and August 31, 2022, Petra said. Botswana Diamonds has the option to buy out the royalty for $2 million in cash.

Petra’s subsidiary Sekaka Diamonds Exploration (Pty) Limited, which Botswana Diamonds would take over, holds three prospecting licences including the KX36 project, which has an indicated resource of 17.9 million tonnes at 35 carats per hundred tonnes.

Botswana Diamonds managing director James Campbell said KX36 would be the company’s most advanced project in southern Africa, and Sekaka’s exploration database would also be “hugely complementary” to its current activities.

Petra, which has been planning to sell Sekaka since June 2018, said the deal is separate to the sales process it announced last month as part of its restructuring.

“The first tranche of the purchase consideration is not expected to be received until August 2021, making the sale too long-dated to help with Petra’s immediate cash flow challenges,” said BMO analyst Edward Sterck.

The sale still requires approval from the Botswana Competition Commission, ministerial consent in Botswana, and approval from Petra’s lenders and debtholders.

Campbell said he hopes the deal will be sealed by August 31.
