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.

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.

Yes, they are a girl’s best friend. But, not every girl can get them and this particular gemstone is definitely a hard-to-get brilliant beautiful bountiful bling.

This diamond has been described as a flawless type IIA with superb polish, excellent symmetry and nil fluorescence. These features are only accorded the top diamonds in the world.

The Venus heart shaped white diamond was cut from a 357-carat rough discovered at the Letšeng Mine in Lesotho in 2015.

It took 1.5 years for the stone to take shape, starting from the initial discovery, going through the analysis process and developing new technology to cut and polish the main diamond and the 22 other satellite stones yielded from the same piece of rough.

This is the 68-carat diamond Lucapa just found at its Lulo mine in Angola Africa

Australia-based Lucapa Diamond (ASX:LOM) has recovered another major rock from trial mining at E46 alluvial terraces — a new area at its Lulo mine, in Angola.

The 68.1-carat gem-quality diamond is one of eight “significant” rocks found at the site, located about 10 km upstream from the alluvial Mining Block 8 and 6, from which Lucapa has been mining diamonds since the firm began commercial operations in January last year.

According to the miner, the finding highlights the potential for widespread recovery of large gems from its Lulo mine, considering the largest individual diamond recovered from the initial exploration bulk sampling phase conducted in the area weighed just 6.9 carat.

Lulo, about 700 kilometers (435 miles) east of Angola’s capital Luanda, is a joint venture between the company and the Angolan government. Lulo is located 150km from Alrosa’s Catoca mine, the world’s fourth largest diamond mine.

The mine hosts type-2a diamonds which account for less than 1% of global supply and, according to Lucapa, the world’s most famous large, white, flawless diamonds belong to this category.

Angola is the world’s No.4 diamond producer by value and No.6 by volume. Its industry, which began a century ago under Portuguese colonial rule, is successfully emerging from a long period of difficulty as a result of a civil war that ended in 2002.

The government has recently reduced taxes and cut state ownership requirements as it seeks to rekindle the industry after the global financial crisis forced mines to close.

Rio uncovers large diamond as prices set for decline

Rio Tinto has unveiled a 187.7 carat rough diamond, as miners predict a decline in rough diamond prices ahead.

The diamond, one of the largest ever discovered in Canada, has been called the Diavik Foxfire, and was uncovered at the Diavik mine just 220 kilometres south of the Arctic Circle.

The unveiling of the rough diamond comes as prices for the stones decline.

Rio Tinto Diamonds managing director, Jean-Marc Lieberherr, explained the reduction in demand from China coupled with a lack of available credit in the industry has wreaked havoc on the sector.

“There is a need for the rough prices to adjust to the economic value of the polished price and that trend is in motion at the moment,” Lieberherr told Bloomberg.

Prices for rough diamonds have fallen by nearly a fifth this year, and expected to continue falling for a sixth quarter.

However there is an expectation that this current situation will reverse mid-next year, as traders and cutters begin releasing supply.

“The polished pipeline is a little bit overloaded and it will probably take until about the middle of next year to come back to normal levels,” Lieberherr stated.

“The last 12 to 18 months have been tough for the industry.”

The larger producers, De Beers and Rio Tinto, have all lowered production in an effort to support prices, while Australian diamond magnates are facing financial difficulties in the low market.

Late last month the second largest single diamond ever – a 1111 carat stone – was uncovered.

This plant may be the best diamond-finding tool you’ll ever have

While money doesn’t grow on trees, diamonds might do. Literally. That seems to be the conclusion of a study conducted in Liberia by a scientist at Florida International University (FIU) in Miami, to be published in the June-July issue of the journal Economic Geology.

Stephen Haggerty, who specializes in diamond research, has found a new prickly, palm-like plant that seems to grow only on top of kimberlite pipes — columns of volcanic rock hundreds of meters across that extend deep into Earth, which are the source of most of today’s commercial diamonds.

The plant, identified as Pandanus candelabrum, could become a simple and efficient tool for diamond hunters in West Africa to uncovering potentially rich precious gems and semi-precious gemstones deposits

The plant, identified as Pandanus candelabrum, could become a simple and efficient tool for diamond hunters in West Africa to uncovering potentially rich precious gems and semi-precious gemstones deposits, the paper claims.

Haggerty, who is also chief exploration officer of Youssef Diamond Mining Company (YDMC), with concessions in Liberia, believes the plant has adapted to kimberlite soils, which are rich in magnesium, potassium, and phosphorus.

The scientist, who has worked in the African nation off and on since the late 1970s, has in recent years focused his prospecting efforts in the northwest part of Liberia.

Two years ago he discovered a new kimberlite pipe 500 meters long and 50 meters wide.

Speaking to Science Magazine, Haggerty said the soil above that pipe has already yielded four diamonds: two in the 20-carat range, and two in the 1-carat range.

According to his bio, posted at FIU’s website, he is currently conducting wide-ranging research, which includes from field activities in Brazil, India, South Africa, and West Africa (finger printing “Blood Diamonds”), “to the cosmos, pre-solar diamonds (greater than 4.5 billion years old), and the enigmatic origin of black and porous carbonado-diamond.”
