An extremely rare 23.16 carat pink diamond was mined in the Williamson mine in Tanzania by Petra Diamonds.

As you surely know, pink diamonds are the most popular choice for diamond connoisseurs, which make this discovery a most significant one.

Pink diamonds are only found in a handful of mines and are the most desired color for diamonds on the market.

The diamond in its rough form will be sold in Antwerp in December.

A previous large pink diamond found was in September 2014 with a weight of 16.4 carat. An anonymous Chinese client purchased it on auction for $2.2 million, as a gift for his daughter.

The current 23 carat pink diamond is far superior in size and in color to its predecessor.

Pink diamonds are believed to owe their color to intense pressure and heat under the earth. These have caused distortions in the crystal lattice which influences the way the diamonds will absorb green light, thus getting a pink reflection.

Colored diamonds constitute only 1% of the world's diamond production and pink diamonds make up 1% of that 1%, as per Richard Revez in a December 2011 interview with the BBC.

The Williamson Mine is currently co-owned by Petra Diamonds and the government of Tanzania, which holds a 25% stake.
