Pink and other naturally colored diamonds possess a beauty that has risen sharply in price and popularity. These rare diamonds attract attention for several reasons.
Their beauty tops the list. Tiny structural variations inside the stone produce colors ranging from light rose-petal pink to deep violets and blues.
Their rarity makes them a status symbol commanding high prices at auction. It is not uncommon to have pink diamonds at auction sell for more than $1 million.
Availability - 90% of the world’s pink diamonds are currently mined from Rio Tinto’s Argyle Mine in Western Australia.
Expectancy - In 2013, Rio Tinto took a break from production to convert the Argyle mine from open pit mining to an entirely underground operation that would expand the life of the mine… by about five years. Rio Tinto has publicly stated this mine may cease production by the year 2020.

Pink diamonds are legendary.
They’ve been found historically in India, Africa, and Brazil. Fabulous old cut pink diamonds have graced the crown jewels of India and France among others.
Instead of the usual kimberlite pipe where most of the world’s diamonds are found, the pink diamonds at Argyle are sourced from a volcanic lamproite pipe.
Most of the world’s current production of pink diamonds comes from the Argyle mine.
There are only an estimated 500 tender-quality pink diamonds left to be discovered in the Argyle mine before it shuts down. There is no other consistent source for pink diamonds.
