The Australian Trilogy, a coin collection featuring a pink, purple pink, and violet diamond from Rio Tinto’s Argyle Diamond Mine, has sold for $1.8 million Australian dollars (about $1.42 million).
The Trilogy was created by the Perth Mint in Perth, Australia, home of the Argyle mine. An anonymous collector from Asia purchased it within a month of its unveiling.
The Australian Trilogy will be exhibited at the Perth Mint until the end of the month.
