Gem Diamonds’ Letšeng mine yields 212 carat stone

Africa focused miner Gem Diamonds has found yet another big precious stone at its prolific Letšeng mine in Lesotho, the third greater than 100 carat diamond mined in September.

The 212.91 carat Type II white diamond was recovered on September 19th, the company said on Monday. It is the thirteenth diamond over 100-carat unearthed this year at the operation, it noted.

Type IIa diamonds are the most valued and collectable precious gemstones, as they contain either very little or no nitrogen atoms in their crystal structure.

The Letšeng mine, owned 70% by Gem Diamonds, is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, it is also one of the world’s most elevated diamond mines.

The operation has a track record of producing large, exceptional white diamonds, which makes it the highest-dollar-per-carat kimberlite diamond mine in the world.

Star Diamond confirms Type IIa high value diamonds at Orion North, Taurus kimberlites

 

Star Diamond has completed a study into the abundance of Type IIa diamonds in parcels recovered from the Early Joli Fou geological units at the Orion North (K120, K147 and K148) and Taurus kimberlites (K118, K122 and K150).

The pipes are located within the Fort a la Corne diamond district of central Saskatchewan, including the Star–Orion South diamond project, on properties held in a joint venture with Rio Tinto Exploration Canada.

These diamond parcels were recovered by Star Diamond between 2006 and 2008 from 120-cm diameter drilling programs. The latest study confirms that unusually high proportions of Type IIa diamonds are present in both the Orion North and Taurus kimberlites.

Of particular note is the high proportion of Type IIa diamonds in the Orion North 147-148 EJF (52%), of which 66% of the 24 stones, 0.66 carats and above are Type IIa. The largest Type IIa diamond identified was a 6.88-carat stone from Orion North (K147-K148 EJF).

Senior technical advisor George Read said that the Type IIa diamonds at Orion North and Taurus are top white in colour, Type IIa diamonds are rare and account for less than 2% of all natural rough diamonds mined from kimberlites. Many high-value, top colour, large specials (greater than 10.8 carats) are Type IIa diamonds, which include all 10 of the largest known rough diamonds recovered worldwide.

The study also confirms and augments an earlier study of Type IIa diamonds being present in the Fort a la Corne kimberlites with Star (26.5%) and Orion South (12.5%).

A target for further exploration completed by Star Diamond in 2014 estimated that between 881 million and 1.04 billion tonnes of the major EJF units, containing between 46 and 79 million carats, occur within the Orion North and Taurus kimberlite clusters.

Orion North (K147, K148 and K220) alone is estimated to contain between 340 million and 410 million tonnes of EJF kimberlite with an estimated range of grade of 2.75 to 8.37 carats per hundred tonnes.

Petra sells 299 carat diamond for $12.18 million

 

Petra Diamonds has sold a 299.3 carat diamond recovered in January at its iconic Cullinan mine, in South Africa, to Belgium-based Stargems DMCC for $12.18 million.

The exceptional Type 11a white gem-quality rock achieved a price of $40,701 per carat, which exceeds the $34,386/ct received for the 424.89 carat “Legacy of the Cullinan Diamond Mine” in May 2019.

The freshly sold find adds to other most famous diamonds unearthed at Cullinan, such as “The Blue Moon of Josephine”. This 29.6 carat blue diamond sold for $48.5 million in 2015, a world record price per carat for any diamond sold at an auction at the time.

The company’s board approved such reorganization in January, and Petra expects to finish the process around the end of March.

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.
