French high jewellery house Messika has unveiled an exceptional necklace featuring one of the rarest natural diamonds ever discovered, the remarkable 20.46 carat Okavango Blue Diamond. The extraordinary gem, recovered from Botswana’s renowned Orapa mine, represents one of the finest blue diamonds ever unearthed and highlights the country’s position as a leading source of exceptional natural diamonds.
The story of the Okavango Blue began in 2019 when a 41.11 carat rough blue diamond was discovered at the Orapa mine. Following an extensive cutting and polishing process, the crystal was transformed into a breathtaking 20.46 carat Fancy Deep Blue VVS2 Type IIb oval diamond, a combination of colour, clarity and rarity seldom encountered in the natural world.
Recognising the significance of the gem, the Government of Botswana commissioned celebrated jewellery designer Valérie Messika to create a one of a kind masterpiece worthy of such an extraordinary diamond. Rather than overwhelming the centre stone, Messika chose a timeless design that allows the blue diamond to remain the undisputed focal point.
The completed necklace features the Okavango Blue suspended within a halo of white diamonds and attached to a collar containing more than 500 meticulously set diamonds. The contrast between the brilliant white diamonds and the deep blue centre stone intensifies the diamond’s remarkable colour while emphasising its exceptional size and beauty.
Messika explained that her objective was to create a design that honoured the diamond itself rather than compete with it. The elegant medallion inspired setting gives the necklace a classic appearance while showcasing one of nature’s rarest geological treasures.
Founded in Paris in 2005, Messika has become one of the world’s most recognised contemporary luxury jewellery brands. Valérie Messika inherited generations of diamond expertise through her father, renowned diamond dealer André Messika, and has built an international reputation for modern diamond jewellery collections that combine technical craftsmanship with contemporary design.
Despite its extraordinary value, the necklace has not been created for commercial sale. Instead, it serves as a celebration of Botswana’s natural diamond heritage and the country’s commitment to showcasing its exceptional mineral resources through world class craftsmanship.
The project also reflects Botswana’s long standing partnership with leading jewellers to promote the value and rarity of natural diamonds on the global stage. Messika previously collaborated with Botswana on another remarkable high jewellery creation featuring a rare 33 carat flawless diamond recovered from the country’s mining industry.
Blue diamonds remain among the rarest gemstones on Earth. Their distinctive colour is produced by trace amounts of boron incorporated into the diamond crystal during its formation billions of years ago under extreme geological conditions. Experts estimate that only a tiny fraction of all natural diamonds display a blue colour, making stones such as the Okavango Blue exceptionally scarce.
The Okavango Blue stands as both a geological marvel and a showcase of exceptional craftsmanship. While many of the world’s finest diamonds ultimately enter private collections, this extraordinary necklace has been created as a symbol of Botswana’s natural wealth and the enduring beauty of rare natural diamonds, demonstrating that some treasures transcend commercial value and become part of diamond history.
