A Vancouver company says it’s unearthed a diamond believed to be the second largest in the world from a mine in Botswana. It's set to join some fairly weighty company in the record books. Here are the top five largest diamonds documented to date:
The rough diamond discovered in 1905 clocked in at 3,107 carats or 621 grams, but the gem earned more notoriety once it had been cut. Some of the pieces from the original have now found their way into the crown jewels of the United Kingdom.
This 971-carat (192-gram) diamond, discovered by accident in 1893 by a worker in a South African mine, was later cut into 10 much smaller stones. One former manager of famed jeweller De Beers described this decision as "the greatest tragedy of modern times in the history of famous diamonds."
Star of Sierra Leone
Iconic jeweller Harry Winston paid handsomely for this diamond, which was discovered in 1972. The stone, weighing 969 carats or 194 grams, fetched just under US$2.5 million in the currency of the day. Six of the 17 smaller gems cut from the diamond were later arranged into the famous Star of Sierra Leone Brooch.
This stone, measuring 890 carats or 178 grams, was reportedly discovered in 1984 by a young girl playing near a mine in the Democratic Republic of the Congo. She found the massive brown diamond among a pile of rubble that had been discarded. It was ultimately cut into 15 smaller gems.
The Golden Jubilee
The world’s largest cut diamond is a sparkling amber colour, coming in at 545.67 carats. It was discovered in a South African mine in 1985 and was blessed by the Pope before finding a home with the King of Thailand, in honour of his 50th coronation anniversary.
