You don’t have to be a diamond insider to know the name “Lesedi la Rona” – the largest diamond discovered in more than a century. In size (the stone measures 6.5 cm by 5.6 cm by 4 cm) it is second only to the 3016.75-carat Cullinan Diamond, which was discovered in South Africa in 1905.
The owner of the uncut stone is Canadian miner Lucara Diamond. In an interview with Channel News Asia back in April 2016, Lucara’s CEO William Lamb talked about the discovery of the diamond, and the much-needed exposure the unearthing of the stone brought to his young company.
According to Lamb, the story begins with a very late night phone call he had missed from Paul Day, his COO in Botswana. Lamb then fearfully returned the call, apprehensive of the news it might bring. He needn’t have worried, though. Day immediately began the conversation with these game-changing news: “Congratulations, you are the CEO of the first company in a 100 years to recover a stone over 1,000 carats.”
Four months later, “Lesedi La Rona” made its first-ever appearance in a private unveiling for 50 selected guests at The Ritz-Carlton Hotel in Singapore. The diamond then embarked on a special “world tour”, visiting five other cities. Now, according to The Telegraph, the 1,109-carat stone is going on display in London. Sotheby’s will sell “Lesedi la Rona” on June 29, expecting it to sell for a staggering world record of £50 million (around $70 million).
