"New record-breaking diamond discovered: 1,758 carats"

Lucara Diamond has unearthed a whopping 1,758 ct. diamond at its Karowe mine in Botswana, which is now considered the second largest piece of rough ever found.

The stone, described as bigger than a tennis ball, dwarfs even the Lesedi La Rona, the 1,109 ct. stunner Lucara found in 2015, which, until last week, held the title as the second-largest piece of rough ever discovered.

The only bigger recorded find is the 3,106 ct. Cullinan, which was discovered in South Africa in 1905.

However, unlike the Lesedi and Cullinan—both of which boasted top color and clarity—this new find was characterized as a “near gem of variable quality,” though it has “domains of high-quality white gem.” The stone is undergoing “further detailed analysis,” a statement said.

If finds of bigger diamonds seem a little more frequent lately, it’s because technology has made it easier to locate them. While in the past, the mining company business model generally called for them to crush their production and then sort through the remains, since 2015, Lucara has used X-ray technology to improve recovery. As a result, 12 diamonds in excess of 300 carats have been recovered at Karowe, including the two record-breaking stones of more than 1,000 carats.
