The Okavango Diamond Company (ODC), the rough diamond distribution company that is wholly owned by the Government of Botswana, has unveiled an oval-shaped polished blue diamond weighing 20.46 carats – “the biggest blue diamond discovery ever made” in Botswana. It will be showcased over the coming months, and is expected to be sold towards the end of 2019.

ODC MD Marcus ter Haar said: “From the first moment we saw the diamond, it was clear we had something very special. Everyone who has viewed the 20-carat polished diamond has marvelled at its unique colouration, which many see as unlike any blue stone they have seen before”. He said the diamond was a “once-in-a-lifetime” find and added that the stone is “about as rare as a star in the Milky Way”.
