The Cullinan Diamond discovered in 1905, weighed at 3100 carats or 1.3 pounds, is the world’s largest diamond. Fredrick Wells who was the manager of the Premier Diamond Company discovered it in South Africa. Wells accidentally found the diamond when it refected light off the mine walls. He initially thought the diamond was a large piece of glass. The diamond gets it name from Sir Thomas Cullinan, who opened the mine.
Sold in 1907 to the South African Government, King Edward VII received it as a gift for his 66th birthday. To transport the diamond to England safely, detectives accompanied the box in a ship that carried a fake diamond as a decoy. The stone was eventually placed in a box and sent by parcel post. The diamond, insured then for $1.25 million, was studied for 3 months, and cut by Asscher’s Diamond Company of Amsterdam.
