Over the years this mine has become the most important source of colored diamonds in the world. It is particularly renowned for its pink, champagne, cognac, violet and finally red diamonds, the rarest color. The Argyle mine closed permanently on November 3, 2020. Gemological point: the colour of these brown diamonds is due -most of the time- to the "graining", that is to say to a succession of brown parallel planes in the gem. Historical point: the most famous brown diamond in the world is the "Golden Jubilee", with a weight of 545,67 carat. This diamond was discovered in 1985 in the Premier Mine in South Africa. It was then cut by the renowned Gabi Tolkowsky. In 1997, it was presented to King Rama IX of Thailand as a tribute to the 50th anniversary of his coronation. This is why it is now called the "Golden Jubilee".
