A rare blue diamond weighing 41.82 carats was recently discovered in the Cullinan mine in South Africa. It is valued at an impressive amount of over 30-40 million euros. The company Petra Diamonds, which found the stone, is considering selling it through an international auction or a private agreement.

Classified as 'Type IIb', the diamond is prized for its clarity and ability to conduct electricity, being among the most valuable in the world. Although it will lose some carats during polishing, it is estimated that it will gain value due to the quality of the cut. Petra Diamonds' shares rose by over 17% after the announcement of the discovery. The Cullinan mine is known for producing exceptional blue diamonds, including the famous Cullinan Diamond from 1905.
