The most valuable gem the world has ever seen was a pink diamond - the Graff Pink - a 24.78 carat Fancy Intense Pink, which sold at auction in 2010 for over USD $46 million.
Due to their extreme rarity, the values associated with the most vividly coloured Argyle pink diamonds, are abstractly high, sometimes reaching into the millions of dollars per carat. In this sense they have more in common with rare, fine art than their distant colourless cousin, the white diamond.
A pink diamond is approximately 20 times more valuable than its white diamond equivalent.
Throughout history pink diamonds have been treasured by royal families the world over, with the most notable being the Williamson Pink - a 23 carat diamond that is currently owned by Queen Elizabeth II.
90% of the world's pink diamonds come from the Argyle Diamond Mine.
Just one tenth of one percent of the Argyle Diamond Mine's production is pink.
The Argyle Diamond Mine's annual production of pink diamonds over half a carat would fit in the palm of your hand. The larger rare violet diamonds would barely fill a teaspoon.
Argyle pink diamonds offer an intensity of colour that is unmatched by any other pink diamond.
Argyle Pink Diamonds' Tender stones are literally one in a million, as for every one million carats of rough diamonds, only one carat of polished is offered for sale at the Tender.
Adding to their rarity, an Argyle pink diamond is incredibly difficult to polish requiring highly skilled, master cutters who specialise only in Argyle pinks.
