Blue moon Tender Diamond

Lot Number: 35

An extraordinary treasure from one of the world's most exclusive diamond collections, this exceptional Round Brilliant Fancy Grey Blue Argyle Diamond bears Argyle ID 409349 and was selected as Lot 35 in the prestigious Blue Moon Tender.

Displaying the coveted BL1 colour grade, this diamond exhibits one of the deepest and most intense blue colour saturations ever produced by the Argyle Diamond Mine. Natural blue diamonds are among the rarest gemstones on earth, with Argyle blue diamonds representing only a minute fraction of the mine's already limited production. Their scarcity is so profound that many collectors will never have the opportunity to acquire one.

The combination of its remarkable P1 clarity, brilliant round cut, and distinguished Blue Moon Tender provenance elevates this diamond into an elite category reserved for the most discerning collectors and investors. The round brilliant cut maximises both brilliance and colour, creating a mesmerising display of light and rare blue saturation.

With the Argyle Mine now permanently closed and only a handful of Blue Moon Tender diamonds ever released to the market, this gemstone represents an exceptionally rare opportunity to own a piece of Australian diamond history. Its rarity, provenance, and enduring desirability place it among the most collectible natural coloured diamonds in the world.
