0.423ct Authentic Australian Pink Oval Diamond of Argyle Origin - PC3

A single 0.423 carat pink Argyle origin diamond, graded PC3 (Pink Champagne 3), part of the NUNA collection. Presented in a premium leather patterned collectors box.

Deep in the remote Kimberley region of Western Australia, the Argyle mine yielded one of the world’s most coveted natural treasures — Argyle origin pink diamonds. Born over billions of years beneath the earth’s surface, these extraordinary gems are renowned not only for their exquisite beauty but for their incredible scarcity.

The Nuna Collection is a rare offering of six individually stunning Argyle origin pink diamonds — all traced back to a single historic Argyle parcel. Together, these six stones total exactly 2.56 carats, preserving the integrity and provenance of their origin. Each diamond is unique, yet they share the same parcel number, making this set a true collector’s piece — a closed chapter of Australian mining history, held in your hands.

These are not just diamonds, they are finite assets, never to be mined again. An enduring investment in beauty and provenance.

An ADV Certificate of Authenticity accompanies the Argyle origin diamonds, including a declaration of origin. ADV Authenticity is assured with a tamper-evident secure seal.
