Argyle Tender Stones
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 Diamonds 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.
The Argyle Colour Grade
The Argyle Method for grading coloured diamonds.
Argyle is the largest producer of pink diamonds in the world and the Argyle Pink Diamond Grading System is an internationally recognised grading system for coloured diamonds.
Natural diamonds regardless of colour are graded and valued according to the well-established and recognised ‘Four Cs’ method
- Carat Weight
For white diamonds, the grading process is fairly rudimentary. However, with pink diamonds, there is one measure that is far more important than the others - and it is the Colour of the diamond; both the actual colour and its intensity. It’s this that determines the value of a pink diamond.
Yes, Clarity is important but it’s secondary to Colour, followed by Carat Weight and Cut. Argyle Pink Diamonds range in colour from the palest blush pinks through to deep red and every shade of the pink spectrum that lies between. The deeper the shade of pink and greater intensity of colour, the rarer and more valuable the diamond. At the far end of this spectrum is Fancy Red Diamonds being so rare that very few people in the world will ever see one.
Gem Identification and Authenticity Document
An Argyle Gem Identification and Authenticity Document is provided with all Argyle diamonds that weigh over 0.l5cts and these can be verified on the Argyle Diamond website for all diamonds issued from 1st January 2009.
As a further security measure, Argyle moved to laser inscribing the girdle of all polished pink diamonds from late 2004. They began the diamonds weighing greater than 0.20ct and then from January 2009 it was expanded to include diamonds weighing greater than 0.l5cts.
