The reserve auction took place at Sotheby’s in London on Wednesday evening.
Lucara Diamond named its 1 111 carat gem quality diamond “Lesedi La Rona” – which means “Our light” in Setswana in February 2016 after it was recovered in November 2015 from the company’s Karowe mine in Botswana.
Lesedi la Rona measures 65 mm x 56 mm x 40 mm in size and is the second-largest ever to be recovered in Botswana.
A 1 111 carat gem quality, Type IIa diamond, an 813 carat stone and a 374 carat stone are some of the largest diamonds to date that were recovered by Lucara Diamond at its Karowe mine.
On 18 January 2016, Lucara Diamond had launched a competition to name the golf ball-sized – Type IIa diamond, where entrants were invited to submit their suggested name and their rationale for their choice.
The giant sized stone is a Type IIa diamond that is a rare and coveted subgroup which comprises less than 2% of all gem-quality diamonds. Stones in this group are the most chemically pure and often show extraordinary optical transparency.
In May, Lucara Diamond sold its 813 ct uncut diamond named “The Constellation,” which it found at the same Botswana mine as the Lesedi la Rona, for $63.1 million.
In the statement issued by Lucara on Wednesday, the company referred to the Lesedi la Rona as being 1 109 carats in size.
