The 71.26-carat rough was discovered at the Ekati mine in northern Canada in 2021 and was purchased by Tiffany & Co the following year.
After previewing the diamond to private clients, the rough was cut into separate 15-carat and 20-carat stones in Antwerp.
Chief gemmologist Victoria Reynolds said that few people understand the beauty and rarity of fancy colour diamonds.
“It’s very rare to find a diamond of this size and saturated colour that came from hundreds of miles in the earth in this near-perfect octahedron structure,” she told Robb Report.
“Most people, even gemmologists, will never see a rough stone in this condition.”
Tiffany & Co has had a renewed focus on exceptional diamonds and gemstones in recent years, purchasing a 10-carat emerald from the Muzo mine in Colombia and 35 pink diamonds from the Argyle in Western Australia.
Reynolds added: "Our artisans handcrafted this rough stone into two gemstones of unparalleled vivid yellow colour and brilliance, transforming nature's miracles through the exceptional skill of Tiffany craftsmanship.”
