Rio Tinto unveils Pink Diamond Coin Trilogy

A $1.8 million coin trilogy boasting rare violet & pink diamonds has been unveiled at the Perth Mint with international buyers already showing interest in the unique collection.

The Australian Trilogy is comprised of three one-kilogram coins struck from gold, platinum and rose gold, with each featuring either a pink, purple-pink or violet diamond, which were unearthed at Rio Tinto’s Argyle mine in the east Kimberley region of Western Australia.

One of the coins, made 99.99% of gold, portrays two kookaburras on a wooden fence looking at a 0.47-carat round brilliant cut fancy deep purple-pink diamond.

The kangaroo coin, crafted from 99.95% pure platinum, depicts the marsupial in an outback plain with a 0.46-carat emerald-cut fancy dark grey-violet diamond.

And the 91.7% rose gold koala coin depicts the animal beneath a eucalyptus tree beside a 0.58-carat emerald-cut fancy intense pink diamond.

The Perth Mint will only ever release one of The Australian Trilogy 2017 Collection, said Rio Tinto in a statement.

The Trilogy is selling for a cool $1.8 million and will be on display in The Perth Mint Shop throughout June, unless sold prior.

The 2016 Kimberley Treasure coin, valued at $1 million, sold to an international buyer within 48 hours.
