“The Queen”: A 3.16-carat Argyle Pink Diamond Sets a New Benchmark in Rarity
GIA Monograph “The Queen”, this Argyle pink diamond is the largest 1P ever certified.
NEW YORK, Sept. 8, 2025 /PRNewswire/ — In an era when natural wonders are becoming scarce, The Queen, a GIA-certified 3.16-carat fancy vivid pink diamond, has emerged as a once-in-a-lifetime treasure. Certified as the largest diamond graded 1P by Argyle Pink Diamonds™, this extraordinary gem surpasses even the legendary Argyle Alpha in size and prestige, securing its place as a historic milestone in the world of colored diamonds.
Since the closure of the famed Argyle Diamond Mine in Western Australia in 2020, the global diamond industry has faced an unprecedented shortage of natural pink diamonds. For decades, Argyle supplied over 90% of the world’s pink diamonds, creating an unmatched legacy of quality and rarity. Today, The Queen symbolizes the pinnacle of Argyle production with no comparable source remaining, demand and value for these stones have soared to record levels.
A Rare 1P Masterpiece
Argyle’s 1P grading is reserved for the rarest, most intensely saturated pink diamonds, and The Queen—the largest ever graded 1P — embodies the best of color, brilliance, and rarity. Originating from a 5.19-carat Argyle rough stone discovered in 1995, the stone was first sold to a De Beers Sightholder before being expertly shaped by London master cutter M. Vainer Ltd, later recut into a modified brilliant cushion, its softened corners and radiant facets create a continuous play of light, making it a jewel of timeless elegance and geological perfection. After decades in private hands, The Queen returned to the market in April 2024. The GIA Monograph confirms: “The Queen is the largest cushion-shaped diamond to have been graded as 1P by Argyle Pink Diamonds™.
A Market Defined by Scarcity
The Argyle mine, opened in 1985, supplied the world with rare pink diamonds, so scarce that only one in 100,000 gem-quality stones was pink. Since its closure, scarcity has intensified. According to the Fancy Colour Diamond Index, between 2005 and January 2025, pink diamonds across all origins, shapes, sizes, and intensities have risen in value by 393.5%, with Argyle-certified stones far surpassing even this growth.
With its unmatched provenance, unique beauty, and emotive backstory, The Queen is set to remain a defining icon in the history of pink diamonds — a jewel as timeless and priceless as the love it was meant to celebrate.
