Argyle Pink Diamonds
Argyle pink diamonds are among the most coveted gemstones in the world — admired for their extraordinary colour, remarkable rarity and increasing value. With the closure of the Argyle mine in Western Australia, these diamonds have become finite pieces of Australian history, treasured by collectors and jewellery lovers alike.
At James Thredgold, we are proud to source, design and craft jewellery featuring certified Argyle pink diamonds. Each stone is chosen for its beauty, provenance and enduring investment potential.
Why Argyle Pink Diamonds Are So Sought After
Argyle pink diamonds represent the rarest 1% of all diamonds discovered globally. Their breathtaking beauty is matched only by their scarcity.
Key reasons for their desirability include:
Exceptional rarity — No new stones will ever be mined from Argyle.
Unique colour chemistry — A combination of lattice distortion and trace elements results in vivid pink hues unlike those found in any other diamond source.
Strong global demand — Collectors and investors continue to drive value upward.
Australian provenance — Their origin adds cultural and historical significance.
The Rarity of the Argyle Mine
Located in the East Kimberley region, the Argyle mine operated for almost 40 years and produced over 90% of the world’s pink diamonds.
When mining ceased in November 2020, global supply became permanently limited.
This closure has transformed Argyle pink diamonds from rare gemstones into legacy assets — finite, irreplaceable and increasingly valuable with time.
What Makes Argyle Pink Diamonds Unique
Every Argyle pink diamond is graded according to its colour hue and intensity — factors that significantly influence both beauty and value.
The Argyle grading system includes Purplish Pink (PP), Pink (P), Pink Rose (PR) and Pink Champagne (PC)
Each category is further divided by intensity on a scale from 1 (most intense) to 9 (lightest).
Unlike white diamonds, Argyle pink diamonds often prioritise colour above size or clarity, making every stone visually expressive and completely unique.
Understanding Colour and Cut
Colour
The most valuable stones display saturated, evenly distributed pink tones.
Some carry subtle violet or rose undertones, while others exhibit warm champagne hues.
Cut
Pink diamonds are often cut to enhance colour rather than maximise size.
This results in captivating brilliance and depth — especially in fancy shapes such as radiant, oval and cushion cuts.
Clarity
Due to their natural formation, inclusions are common.
What matters most is how the diamond performs visually; Argyle pink diamonds with vibrant colour often remain highly prized regardless of minor inclusions.
Investment Value and Collectability
Argyle pink diamonds have shown exceptional value growth over the past two decades, with premium stones achieving record prices at auction and in private markets.
Their investment appeal stems from:
- finite supply following mine closure
- consistent global demand
- strong historical price appreciation
- desirability among collectors
- verified provenance and certification
High-quality stones — particularly those with intense colours or unusual sizes — are now considered modern investment gems.
Certification and Provenance
Every Argyle pink diamond we source is accompanied by:
- Official Argyle Lot Number
- Authentic Argyle Certificate of Origin
- Detailed grading information
- Additional certification where applicable (e.g., GIA)
This documentation verifies authenticity and is essential for long-term value and future insurance or resale.
