Botswana’s state-run Okavango Diamond Company unveiled on Wednesday what is believed to be the largest blue diamond ever discovered in the southern African country, one of the world’s top producers.
The 20.46 carats, oval-shape fancy precious rock has been named “The Okavango Blue” in honour of the Okavango Delta, the country’s wildlife-rich world heritage site.
From all coloured diamonds, blue ones are the most unusual and that’s why the miner says its find is one of the rarest in the world.
“It is incredibly unusual for a stone of this colour and nature to have come from Botswana – a once-in-lifetime find, which is about as rare as a star in the Milky Way,” Okavango Diamond Company managing director Marcus ter Haar said in a statement.
The 20.46 carats, oval-shape fancy precious rock has been named “The Okavango Blue” in honour of the Okavango Delta, the country’s wildlife-rich world heritage site.
“It sits in the very top bracket of all-time historical blue diamond finds [especially because] only a very small percentage of the world’s diamonds are classified as fancy colour,” he noted, adding the company expects to sell it by the end of the year.
In 2016, a massive intense blue diamond, known as The Cullinan Dream, sold for $25.4 million at a Christie’s auction in New York, breaking all records and becoming the most expensive gem of its kind ever sold at auction.
Last year, a 6.16-carat blue diamond, secretly passed down through European royalty over three centuries, fetched $6.7 million at a Sotheby’s auction in Geneva — $1.4 million more than what experts expected it to be sold for.
Arguably, the most famous is the Hope Diamond, also known as Le Bijou du Roi (“the King’s Jewel”), Le bleu de France (“France’s Blue”), and the Tavernier Blue. The massive, 45.52-carat, deep-blue diamond is now kept at the U.S. National Museum of Natural History in Washington, D.C.
Botswana, which was overtaken by Russia as the world’s top diamond producing country in 2014, is grappling with aging mines, as well as power and water shortages.
Still, diamonds are the country’s main source of income and account for about 80% of its exports.
The nation is home to some of the world’s most prolific diamond mines, including Lucara Diamond’s (TSX:LUC) Karowe operation, where the now-famous Lesedi la Rona, the second-largest gem-quality diamond to ever be found, was unearthed in 2016.
Besides diamonds, the country also produces nickel, copper, coal and iron ore.
