12 Carat Blue Diamond Found in Lesotho

Blue diamonds are among the rarest diamonds out there, and a mine in Lesotho just hit the jackpot with the discovery of a 12 ct. one.

On Sept. 30, Gem Diamonds’ Letšeng mine discovered not only the 12 ct. blue, but an 83.9 ct. white described as “exceptional quality.” The mine’s statement did not comment on the blue stone’s quality.

“Both of these diamonds are expected to fetch good prices at Letšeng’s tenders held in Antwerp, Belgium,” the company added. 

The value of blue diamonds can be seen in the record prices they fetch at auction. On April 24, a 5.3 ct. fancy deep-blue diamond sold for $9.6 million at Bonhams’ Fine Jewellery sale in London—setting a per-carat record ($1.8 million) for a diamond that color. 

This isn’t the only major blue diamond discovery this year: In April, Petra Diamonds announced it had found a 25.5 ct. blue in South Africa.
