Canada’s Lucara Diamond has dug up a 1,094 carat diamond from its Karowe mine in Botswana.
This is the sixth diamond weighing more than 1,000 carats to be recovered at the mine, and it comes only weeks after the recovery of a 2,492 carat diamond the second-largest diamond ever recovered.
“This remarkable stone bears striking similarities to the 692 carat diamond announced in August 2023, which was polished by HB Antwerp and yielded polished diamonds that sold for in excess of $13 million,” the company said in a press release.
“This newly recovered 1,094 carat stone will also be polished by HB Antwerp, as part of the ongoing partnership between the two companies,” Lucara said.
The Karowe mine has produced several large diamonds in recent years, including the 1,758-carat Sewelô in 2019, the 1,109 carat Lesedi La Rona in 2015, and the 813 carat Constellation, also in 2015. The mine is also credited for having yielded Botswana’s largest fancy pink diamond to date, the Boitumelo.
Botswana is the world’s largest producer of diamonds, and the trade has transformed it into a middle-income nation.
Karowe remains one of the highest margin diamond mines in the world, producing an average of 300,000 high value carats each year.
Shares of Lucara rose 8% by 11:40 a.m EDT in Toronto. The miner has a market capitalization of C$221 million ($162 million).

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.
Petra Diamonds announced that it had recovered a 138.57-carat, Type IIa, D-colour diamond at its historic Cullinan mine near Pretoria in South Africa. The company said the diamond would be offered for sale in Johannesburg later this month.

De Beers cut the size of the sight to $250 million and reduced the prices by 9 percent, according to sight holders.
De Beers has also contributed tens of millions to a jewellery advertising campaign. Its advertising campaign will promote diamond jewellery in the U.S. and to Chinese consumers.
The American Gem Society, in partnership with Verichannel, announced today the launch of a specialized search engine for diamonds graded by AGS Lab, available from AGS suppliers.
The online service is integrated into the members only section of the AGS website, and is also accessible to AGS members from the Verichannel platform itself. “AGS Diamond Search” consists of a database of stones uploaded by AGS suppliers, and also stones uploaded directly from the AGS Lab, immediately after being graded, based on permissions set by the supplier. They are searchable using standard criteria of color, clarity, shape, etc. AGS retailers contact suppliers directly to initiate a purchase.
“We’re very pleased to be able to make this resource available as a member benefit for AGS retailers and suppliers,” said Ruth Batson, AGS Chief Executive Officer. It makes sense to give our retail store buyers the most convenient means possible of finding AGS stones from AGS suppliers, essentially all in one place, and right there at our website.”
“We have already uploaded hundreds of stones into the AGS Diamond Search,” said Charles Rosario, Senior Vice President of Lazare Kaplan International Inc., an AGS supplier. “Given that this is a very targeted and exclusive environment, it provides a means of reaching out to AGS stores directly and efficiently.”
Verichannel created the concept of labs uploading diamonds online, immediately after being graded, when it launched its Daily Diamond Report service in January. “The same technology is being used for AGS Diamond Search,” noted Jacques Voorhees, president of Verichannel. “In today’s diamond market, buyers and sellers need to be able to communicate with each other as efficiently as possible, especially when it comes to finding the right diamond, and finding it quickly.”
“At the AGS Lab, we provide a direct feed of freshly graded diamonds to Verichannel’s database, with authorization from suppliers,” explained Peter Yantzer, Executive Director of Gemological Services for the AGS Lab. “These then instantly become part of the AGS Diamond Search system on the AGS website. It’s the fastest way imaginable to get a stone to market.”
“AGS Diamond Search will be a big time saver,” noted AGS retailer Tom Wright, of Wright’s Jewelers, Lincoln, Nebraska. “We’ll begin using this resource as soon as we’re back from Conclave.”
More information on AGS Diamond Search is available at www.ags.org and also at www.Verichannel.com.
