Lucara sells world’s second-largest diamond for $53 million

The tennis ball-sized Lesedi La Rona rough diamond that Lucara Diamond (TSX:LUC) unearthed two years ago at its Karowe mine in Botswana was sold this week for $53 million.

The buyer, London-based Graff Diamonds, paid nearly $47,777 per carat.

“The stone will tell us its story. It will dictate how it wants to be cut, and we will take the utmost care to respect its exceptional properties,” said the gem’s new custodian, Laurence Graff, in a press release.

On the other hand, Lucara CEO William Lamb stated that Graff paid a fair price for the 1,109-carat diamond, whose discovery marked a defining moment for the Vancouver-based company.

Such finding, he said, “solidified the amazing potential and rareness of the diamonds recovered at the Karowe mine. We took our time to find a buyer who would take the diamond through its next stage of evolution.”

An impressive flawless 163-carat diamond that has been hailed the “world’s most beautiful” will go under Christie’s hammer in Geneva in November, the auction house said Thursday.

A team of ten diamond-cutting specialist were involved polishing the rough diamond during the period of 11 months. The stone was then designed into a one-of-a-kind piece by Swiss jewellery house de Grisogono.

The D-color, emerald-cut diamond is classified as a rare Type IIa one, which in technical terms means an almost complete absence of nitrogen in the stone, de Grisogono said in a separate statement.

Alrosa Russian Diamond mine finds gigantic pink diamond, likely its most expensive one

Russia’s Alrosa (MCX:ALRS), the world’s top diamond producer by output in carats, has unearthed 27.85-carat pink precious rock the company believes could be the most expensive it has ever found.

Alrosa is trying to decide on whether to sell this pink rock as a rough diamond, or cut and polish it.The miner, majority-owned by the Russian government, said the gem-quality stone was found at its alluvial mines in Russia’s Far East, adding that the largest pink diamond it had previously discovered was less than 4 carats in weight.

The impressive pink rock, measuring 22.47 mm x 15.69 mm x 10.9 mm, has very few flaws and could become the company’s most expensive polished diamond if it decides to cut it, Alrosa said in the statement.

Coloured diamonds, especially pink ones, have been lately setting records in auctions. In April, Sotheby’s sold a 59.6-carat one — the ‘‘Pink Star’’ — for $71.2 million. Until then, the most expensive diamond ever sold at auction was the “Oppenheimer Blue,” which fetched 56.8 million Swiss francs (more than $57 million at the time) in May 2016.

The previous world auction record for a pink diamond was $46.2 million for the 24.78 carat “Graff Pink” in 2010.

Alrosa noted that it is currently trying to decide on whether to sell this pink rock as a rough diamond, or cut and polish it.

Yet Another huge diamond unearthed in Lesotho mine

Gem Diamonds discovered this high quality 126-carat, D colour Type IIa rock at Letšeng

Africa-focused Gem Diamonds (LON:GEMD) unveiled Thursday a 126-carat rock unearthed at its flagship Letšeng mine in Lesotho, the latest in a string of major discoveries at the operation this year.

The finding of the high quality D colour Type IIa diamond comes barely a month after the company discovered two massive diamonds at the same mine —  a 151.52-carat Type I yellow rock and a high quality 104.73-carat, D-colour Type IIa stone.

It also follows the recovery of a 114-carat diamond in April and an 80-carat, D-colour Type-II diamond found in May — one of the highest-quality diamonds to come out of the Letšeng mine.

Type IIa diamonds contain very little or no nitrogen atoms, which places them among the most expensive stones.

Since acquiring Letšeng in 2006, Gem Diamonds has found four of the 20 largest white gem quality diamonds ever recovered, which makes of the mine the world’s highest dollar per carat kimberlite diamond operation.

At an average elevation of 3,100 metres (10,000 feet) above sea level, Letšeng is also one of the world’s highest diamond mines.

Gem Diamonds finds two large rough diamonds at flagship mine in Lesotho Africa

Africa-focused Gem Diamonds (LON:GEMD) has discovered two diamonds bigger than 100 carats at its Letšeng mine in Lesotho, which should help the company boost revenue and investors confidence.

The two massive diamonds are a 151.52-carat Type I yellow rock and a high quality 104.73-carat, D-colour Type IIa stone, the London-based miner said in a statement.

The last time Gem Diamonds had made a significant discovery at its Letšeng mine before April this year was in 2015.The findings come on the heels of other key discoveries at the mine. In April, the company announced the recovery of a 114-carat diamond and last month it found one of the highest-quality diamonds to come out of the Letšeng mine — an 80-carat, D-colour Type-II diamond.

The last time Gem Diamonds had found a significant diamond in Lesotho was in 2015, when it unearthed an “exceptional” 357-carat rock, later sold for $19.3 million.

Investors reacted positively to the news, with the stock was trading at 1.64% higher at 93 pence around 2:00PM GMT.

Alrosa finds 62.75-carat diamond at prolific Jubilee pipe mine in Russia

Russia’s Alrosa (MCX:ALRS), the world’s top diamond producer by output, said Tuesday it found a 65.75-carat precious rock at the Jubilee kimberlite pipe of its Aikhalsky Mining unit in Yakutia, northeast Russia.

The transparent crystal, the miner said, has an octahedron-shape, light-yellowish tint and its measures 23 x 16 x 17 mm.

Alrosa’s Jubilee pipe is famous for its large finds. Several diamonds from 50 to 138 carats were recovered from the deposit in the past two years, including a 76.07-carat diamond, which was named in honour of 70 Years of the Soviet Union’s Victory in the Great Patriotic War of 1941-1945 against Nazi Germany.

The company’s business unit Aikhal Mining accounted for over 30% of Alrosa’s total raw diamonds in 2016. It generated 12.2 million carats, worth $1.2 billion, according to the firm.

Pink Star diamond sets new world auction price record in Hong Kong

 

A rare diamond known as the Pink Star has been sold in Hong Kong for more than $71m (£57m), setting a new world record for any gemstone at auction.

The oval-shaped 59.6 carat stone was bought after just five minutes’ bidding at Sotheby’s, reports said.

It is the largest polished diamond in its class to go under the hammer.

It sold for $83m in Geneva in 2013 but the buyer later defaulted. The record until now was held by the Oppenheimer Blue, which sold for $50m last May.

Bidding for the gem, which was found by De Beers at a mine in Africa in 1999 and cut over a period of two years, began at $56m.

Sotheby’s said the buyer was Hong Kong jewellery retailer Chow Tai Fook Jewellery.

Alexander Breckner, head of diamonds at jewellers “77 Diamonds”, told the BBC that the stone was exceptional.

“It’s the largest pink diamond ever found in the history of humankind. It’s an incredible colour to it.

“And the sheer size of the stone already makes it so rare and so beautiful.”

Previous records set in stone

May 2016: A large diamond known as the Oppenheimer Blue set a new auction record, reaching a price of $50.6m (£34.7m at the exchange rate then current). The 14.62-carat gem was sold after 20 minutes of phone bidding at Christie’s auction house in Geneva. The buyer’s identity is unknown.

November 2015: The Blue Moon, a 12.03-carat ring-mounted blue diamond, caught the eye of Hong Kong tycoon Joseph Lau, who paid a record $48.4m (£31.7m) for the cushion-shaped stone. He bought it for his seven-year-old daughter, renaming it the “Blue Moon of Josephine” after her.

May 2015: An unnamed buyer made history after purchasing the Sunrise Ruby, a 25.59-carat “pigeon blood” coloured gemstone, for $30m (£19.1m). At that price, it became the world’s most expensive precious stone other than a diamond.

November 2013: The “largest vivid orange diamond in the world”, according to Christie’s, attracted the highest price paid per carat for any diamond at auction, selling for $35m (£22m), or $2.4m (£1.5m) per carat.

November 2010: The Graff Pink, a 24.78-carat “fancy intense pink” stone described as “one of the greatest diamonds ever discovered”, auctioned for $46.2m (£29m). At the time it was believed to be the most expensive gemstone bought at auction and was sold to the well-known British dealer Laurence Graff.

Lucara gets almost $18M for fragment of its massive ‘Lesedi La Rona’ diamond

Canada’s Lucara Diamond (TSX:LUC), the company that hit the jackpot in 2015 after finding the world’s second-largest diamond, just got $17.5 million for a piece that broke from that rock, the now historic 1,109-carat “Lesedi La Rona.”

To date, Lucara has sold 145 diamonds for more than $1 million each.The 373.7-carat diamond, sold during the Vancouver-based miner’s $54.8 million recent tender to luxury jeweller Graff Diamonds, was one of 15 large and high value rocks offered by the company.

Just like the 1,109-carat diamond it found in 2015, all the stones sold this week were mined at Lucara’s Karowe mine in Botswana, which has been yielding massive rocks as of late.

Last year, the miner sold one of those mammoths — the 813-carat “The Constellation” — for $63 million, setting a new record for a rough gem.

It wasn’t that lucky when it came to three-billion-year-old “Lesedi La Rona,” meaning “our light” in the Tswana language spoken in Botswana, as the rock failed to sell at a Sotheby’s auction in June last year.

This is the 373.72-carat rock, once part of the second largest gem quality diamond ever discovered. (Image courtesy of Graff Diamonds.)

The gem, second in size only to the Cullinan diamond in the British Crown jewels, was expected to go for at least $70 million. The highest bid, however, was around $61 million, leaving it in Lucara’s hands.

To date, the company has sold 145 diamonds for more than $1 million each, bringing in revenues of more than $528 million, its President and CEO William Lamb said in the statement.

Botswana, the focus of Lucara, is the world’s largest producer of diamonds and the trade has transformed it into a middle-income nation.

In the elite world of fancy coloured diamonds, green and red are by far the rarest body colours. The appearance of green in a diamond is caused by millions of years of exposure to a source of natural irradiation in the earth, either among uranium compounds or percolating groundwater, which changes its specific absorption of light. Our upcoming New York sale presents a cut-cornered square mixed-cut Fancy Vivid Green diamond weighing 1.64 carats, flanked by two cut-cornered triangle-shaped diamonds weighing approximately .65 carats.

HUGE 110 CARAT YELLOW DIAMOND UNEARTHED IN AFRICAN Liqhobong MINE

Shares in Africa-focused Firestone Diamonds (LON:FDI) shot up in London Wednesday after it announced it had unearthed an 110-carat yellow diamond, it’s biggest find so far, at its newly developed mine in Lesotho.

The company, which is just ramping up production at its Liqhobong operation, said the finding confirmed its belief that the deposit holds large stones.

Investors reacted positively to the news, with the stock climbing as much as 13% early in the day and trading 9.7% higher to 49.10p at 1:38PM GMT.

Firestone spent $185 million building Liqhobong, which boasts over 11 million carats in reserve. The total open pit resource contains over 17 million carats down to 393 metres.

Since production began at Liqhobong in October, and before today’s announcement, the company had recovered 20 stones larger than 10.8 carats, the industry cut off for an exceptional stone, including a 37-carat white diamond.
