Finding rough diamonds is not an easy task, and locating those over 100 carats is exponentially more difficult. Having formed in the earth billions of years ago, most of these stones naturally come in smaller sizes. However, using special X-ray equipment and with a little help from high-value deposits, miners have managed to retrieve quite the handful of large specimens.
Ranging from 203 carats to a massive 2,488 carats, these stones broke scales across the mining industry.
