Since 1985, Argyle pink diamonds has held a highly prestigious and exclusive annual event to sell their most exceptional and desirable diamonds for the year. Known as the Argyle pink diamond tender, it usually comprises 40-60 of the best pink diamonds in the world.
The most valuable diamond in each tender is given the honorary title of “hero stone” and occasionally this will be a rare brilliant red or violet blue diamond. When the Argyle tender includes either of these, it attracts enormous attention due to its rarity and value.
The tender collection travels the world to be presented at private viewings exclusively for collectors and investors. Only the most prominent members of the diamond industry are invited by Argyle to have the opportunity to view and inspect the tender diamonds. Each diamond offered is a rare and individual piece of natural beauty. Each is given a special Argyle tender lot number for that particular year and presented in a handmade box.
Each tender diamond is featured in a prestigious book. Printed by Argyle each year, it’s a work of art in itself, and a copy is presented by Argyle to each successful bidder. These diamonds which can range anywhere from US$100,000 to well over US$1,000,000. Only those invited can make a bid that remains secret and must be submitted to Argyle by an exact date and time.
Pink Kimberley has received the honour of participating and bidding in Argyle's yearly tender auctions. However, since the Argyle mine is no longer operational from November 2020, these tender diamonds are becoming rarer and more exclusive.
