In practice, the Cullinan diamond, discovered in South Africa in 1905, remains the largest gem-quality rough diamond ever found, weighing an astonishing 3,106. Because of that, among these, one stone has captivated the world not only for its brilliance but for its sheer size. 75 carats. The question of what is the largest diamond in the world leads us to a remarkable tale of geology, history, and human ingenuity. Its discovery changed the landscape of the diamond industry and set a benchmark for size that no other gem has since surpassed in its category.
The Cullinan diamond was unearthed at the Premier Mine in Cullinan, near Pretoria, by Frederick Wells, the mine's superintendent. Day to day, the rough diamond's immense size and exceptional clarity made it a prized possession, eventually leading to its purchase by the Transvaal government for £150,000 as a gift for King Edward VII. Its discovery was met with both excitement and skepticism, as such a massive, flawless crystal was unprecedented. The stone was named after Thomas Cullinan, the mine's owner. The stone's journey from a remote mine to the royal collections of the United Kingdom is a fascinating chapter in gemological history.
