ARGYLE | PINK DIAMANTER

Discover our carefully selected collection of rare pink diamonds from the Argyle mine. Each diamond is accompanied by certificates from both Argyle and GIA (Gemological Institute of America).

MILLIONS OF CARATS. ONLY A FRACTION IN PINK.

Since 1985, the Argyle mine in Western Australia was one of the world’s most important sources of diamonds. What made Argyle truly exceptional was its production of natural pink diamonds - a color for which no other mine became as renowned.

For decades, Argyle supplied the vast majority of the world’s pink diamonds, yet they represented only a tiny fraction of the mine’s total output. Only a small number were suitable for fine jewellery.

When the mine closed in 2020, the world lost its most consistent source of pink diamonds. Their finite supply and distinctive provenance have since made Argyle pink diamonds especially sought after by collectors and connoisseurs.

SILENT LUXURY IN ITS PUREST FORM

Argyle pink diamonds represent a quiet expression of rarity. Their appeal lies not in scale or visibility, but in distinctive color, provenance and scarcity.

For those who understand them, an Argyle pink diamond is a discreet signature of exclusivity - a natural diamond from a source that can never be recreated.

Since the closure of the Argyle mine, this sense of rarity has only become more pronounced.

Mining operations at Australia’s iconic Argyle mine ceased on November 3, 2020, marking the end of an extraordinary chapter. Today, the site is undergoing an extensive rehabilitation process, with infrastructure removed, landscapes restored, and the area re-vegetated. Completion is anticipated in the first quarter of 2026.

TENDER KOLLEKTION | ARGYLE

The Argyle Tender was an annual and highly exclusive presentation of the finest and rarest diamonds unearthed from the Argyle mine each year. The first Tender took place in Antwerp in 1985 and featured just 33 diamonds. By the following year, Geneva was added as a viewing location, and as interest grew, cities such as New York, Hong Kong, London, Perth, and Tokyo became part of the international showcase.

From 1985 to 2021, between 50 and 70 of the most exceptional pink, red, blue, and violet diamonds mined annually at Argyle were offered for sale through this prestigious auction. Since 2008, the most remarkable stones in each Tender collection have been given names reflecting their historical significance.

This exclusivity underscores the extreme rarity of Argyle’s pink diamonds—mine data indicates that, on average, only one carat of Tender-quality diamond was discovered for every one million carats of rough diamonds extracted from the mine.

NATURE’S RARE TREASURES

Limited supply
Natural pink diamonds are exceptionally rare, and the closure of the Argyle mine in 2020 permanently reduced one of the world’s most important sources.

Natural color
Unlike many other fancy color diamonds, pink color is not primarily caused by trace elements. It is associated with structural changes within the diamond’s crystal lattice, although the precise mechanism remains complex.

Strong demand
Their limited supply, distinctive color and documented provenance continue to make natural pink diamonds highly sought after by collectors and jewellery connoisseurs.

KEY HIGHLIGHTS | WHAT YOU SHOULD KNOW

Rarity
Rarity is one of the defining factors in the value of a natural diamond. Exceptional stones are typically considered individually rather than by quantity.

Certification
A GIA certificate provides internationally recognized documentation. Diamonds originating from the Argyle mine should also be accompanied by Argyle documentation where available.

Time horizon
Rare diamonds are generally considered a long-term asset rather than a short-term purchase.

A GLIMPSE IN A TERMITE MOUND

Forty years ago, in the Kimberley region of Western Australia, geologists Frank Hughes and Warren Atkinson discovered a small diamond in a termite mound.

What had been brought to the surface marked the beginning of one of the world’s most significant diamond discoveries. After years of exploration, the site of the Argyle mine was identified - a mine that would later become renowned for some of the world’s most distinctive pink diamonds.
