The Argyle Pink diamonds tender

The finest and rarest diamonds are reserved for the annual Argyle Pink Diamonds Tender, which over more than three decades, has established itself as the most exclusive diamond sale in the world. The event highlights a small number of important diamonds that stand apart from their peers in terms of vibrancy and intensity of colour.

The Argyle Diamond Mine is the world’s most important source of pink diamonds and accounts for around 90 per cent of the world’s pink diamond supply. To put this rarity in perspective, of the approximately 130 million carats of rough diamonds produced in the world each year, less than 20,000 carats are rough pink diamonds. Pink diamonds therefore comprise less than 0.01 per cent of global diamond production – tantamount to exclusivity, by any measure.

An entire year’s worth of Argyle pink diamonds over half a carat would fit in the palm of your hand. And the gems from this sprinkling that make it to the tender exemplify the pinnacle of production.

The first tender took place in 1984 when 33 stones were offered with a total weight of just over 18 carats. Even this modest number created a sensation in the diamond industry. Never before had such a collection of high quality pinks been seen together. Most tenders now offer around 50-60 stones annually.

Argyle pink diamonds are coveted by many, but owned by few. The tender is only open to specially selected diamantaires and collectors by invitation.

Private tender viewings are held in Hong Kong, New York and Sydney, with past tenders having travelled to Antwerp, Geneva, London, Tokyo, Singapore, Mumbai, Shanghai and Beijing. Around 150 connoisseurs, collectors and luxury jewellers are invited to place sealed bids on the diamonds. Prices for these diamonds can exceed millions per carat.

The world’s passion for these stones has only intensified through the tender and the price of Argyle pink diamonds has risen steadily year-on-year. Argyle pink diamonds continue to outperform major equity indices. And as is the case with the acquisition of fine art, set rules simply do not apply.
