Diamond Grading LabsAnother amazing diamond was discovered at the Premier Mine, renamed the Cullinan Diamond Mine, in South Africa. The mine is known for the famous Cullinan diamond discovered in 1902. When found, that diamond rough crystal weighed a whopping 3,106.75 carats and is the largest diamond ever discovered.

The announcement came on Tuesday, September 9, 2014 that another notable diamond was discovered at the Cullinan Diamond Mine. This diamond rough crystal weighs 232 carats and is D color with high clarity, consistent with other high quality diamonds found in this mine.

According to the press release from Petra Diamonds, owner of the mine: “Cullinan is renowned as a source of large diamonds and frequently yields diamonds larger than 10 carats. Furthermore, it has produced just under 800 stones weighing more than 100 carats, over 130 stones weighing more than 200 carats, and around a quarter of all diamonds weighing more than 400 carats.

In its history, the mine has produced four of the top 20 largest high quality gem diamonds: The Cullinan (3,106 carats rough), The Golden Jubilee (755 carats rough), The Centenary (599 carats rough) and The Cullinan Heritage (507 carats rough). The Cullinan Heritage was recovered by Petra in 2009 and sold in February 2010 for US$35.3 million, being the highest price on record for a rough diamond.”
