The pinnacle of the Perth Mint’s long-term association with Rio Tinto and Argyle Pink Diamonds, the Australian Trilogy is an incomparable combination of precious metals and rare, natural, fancy-colored diamonds unearthed from the Argyle Diamond Mine in the east Kimberley region of Western Australia.

“This coveted collection of diamond-studded gold and platinum coins has raised the bar on the concept of ‘unique collectable,’ exemplifying the quality craftsmanship for which the Perth Mint and Argyle Pink Diamonds are renowned,” said Perth Mint chief executive officer Richard Hayes.

Since the extraordinary collectable was unveiled by the premier of Western Australia, the Honorable Mark McGowan MLA, last month at the Mint, it has commanded the attention of diamond connoisseurs, investors, and collectors across Australia and overseas.

While several discerning parties expressed interest in purchasing the rare treasure, it was sold via Glajz-THG Pte Ltd. to an anonymous Asian collector.

Singapore-based Glajz-THG Pte Ltd. is a joint venture between Mr. John Glajz and a publicly listed company called the Hour Glass Ltd., specializing in the global distribution and marketing of rare gemstones and luxury fine jewelry.

“The prompt sale of the Australian Trilogy again highlights the premium collectors place on exclusive items, which is what we also found with the sale of the Kimberley Treasure $1 million coin in 2016,” Mr. Hayes continued.

In a convergence of color and light, this extraordinary collectable embodies the essence of the Australian outback—its unique wildlife, rural landscapes, and stunning natural treasures.

With the permission of its new owner, the Australian Trilogy 2017 1-kilogram collection will remain on display in the Perth Mint Shop at 310 Hay Street in East Perth until July 31, 2017.

    Just too expensive to buy this coin set. In fact I cannot afford to purchase this rare gold and platinum 3 coin set. And also this coin set has been sold out.
