Rio Tinto is commemorating the opening of the Argyle underground mine with a limited-edition pink gold ingot hand-set with pink diamonds.
Only 168 one-ounce ingots will be produced by the Perth Mint.
“We are delighted to partner with the Perth Mint on the exclusive release of this distinctive investment piece,” said Kim Truter, managing director of the Argyle Diamond Mine. “It is a beautiful symbol of the unique Argyle story and the recent milestone commencement of underground mining.”
Argyle’s pink diamonds were formed more than a billion years ago below the Earth’s surface under the ancient boab trees in the East Kimberley region of Western Australia. A boab tree engraved on the ingot symbolizes their origin. Each ingot—which is valued at $4880—is individually numbered and comes with a certificate of authenticity.
