One of the biggest diamonds ever found has been unearthed in Botswana: A 998-carat rough diamond was discovered in Botswana in the Karowe Diamond Mine owned and operated by Lucara Diamond, a mining company that specializes in unearthing large diamonds. It could be the fourth-largest gem-quality diamond ever discovered.
The diamond, which measures 67x49x45mm, was recovered from direct milling of ore sourced from an area in the open-pit mine that has recently resulted in discoveries of diamonds weighing 273, 105, 83, 73, and 69 carats. Lucara announced the discovery Tuesday night.
Eira Thomas and Catherine McLeod-Seltzer who founded Lucara Diamond invested in untested equipment and technology for the Karowe mine specifically designed to unearth exceptionally large diamonds. The 998-carat diamond represents the second 500-plus carat diamond recovered from the mine in 2020. Those two diamonds are among 31 diamonds of greater than 100 carats, with 10 of those diamonds greater than 200 carats, the mine has produced this year. The two largest are the 549-carat “Sethunya,” and the most recent 998-carat discovery, which has yet to be named.
