Largest Rough Diamonds Ever Found
Key Findings
About This Dataset
Largest Rough Diamonds Ever FoundThe Cullinan (3,106.75 carats) has stood unbeaten for over a century and still dwarfs the field by more than 600 carats over the 2024 Motswedi (2,492). What stands out is geography and timing: every other stone in the top eight came from Botswana, and five of them were unearthed between 2019 and 2025. That surge reflects modern XRT sorting technology at the Karowe mine, which detects giant crystals before they are shattered by crushing. Below the two multi-thousand-carat leaders the list settles into a 1,098-2,036 carat range, showing that while thousand-carat finds are now almost routine, matching Cullinan's scale remains vanishingly rare.
