5 of the Largest Diamonds Ever Discovered

This diamond was discovered an a South African Mine, Premier Mine and weighs approximately 3106.75 carats! It was discovered in 1905 by Captain Frederick Wells, who was the superintendent of Premier Mine. When he was performing a daily inspection of the mines he saw a magnificent flash of light, the wall of the shaft he was inspecting. He then realized it was a partially exposed crystal,  first he thought it was a shard of glass, placed there as a joke. Using only a pocket knife he managed dug out the crystal. It was immediately sent for inspection and weighed in over 600 grams! The stone was then sent to Asscher Brothers for a cutting where it was then sized into 9 diamonds. The estimated value is over $2 billion dollars. The diamonds were given to the British Royals and now is part of the Crowned Jewels collection. It is rumored that Frederick Wells actually broke off a chunk for himself and the diamond was much larger in size. This has never been proven though.

The diamond was later cut into 10 smaller diamonds, including one of the largest pear shaped diamonds to this date, weighing 69.68 carats. The stone was discovered in 1893 by a worker who was shoveling gravel and loading it into his truck. He did not hand the diamond over to his overseer, but instead gave it directly to the Mine Manager, who rewarded him with £500 in cash and a horse with a saddle and bridle! The day the diamond was discovered the contract between the Mining Company and the syndicate of firms in London which bought its diamonds had been terminated.
