The Okavango Blue
April 20 | Geology.com
The Okavango Blue: In April 2019, the Okavango Diamond Company, a company wholly-owned by the government of Botswana, presented the "Okavango Blue", a 20.46-carat blue diamond. The Gemological Institute of America graded the color of the gem as Fancy Deep Blue, and its clarity as VVS. It was cut from a 41.11-carat rough diamond discovered at the Orapa Mine in Botswana. The company will promote the gem through Fall 2019 and plans to sell it by the end of the year. Photo by Okavango Diamond Company.

Sikhote-Alin Iron Meteorite: A spectacular example of the Sikhote-Alin iron meteorite, which fell in eastern Russia in 1947. This large specimen weighs 11.1 kg / 24 1/2 lbs and is described as a complete individual, as opposed to shrapnel specimens which are angular as a result of explosive fragmentation in the atmosphere. The scale cube pictured, is 1 cm in size. Note the sculptural shape and abundant regmaglypts (thumbprint-like indentations), caused when the surface melted during flight.

A simplified diagram of the Atlantic Meridional Overturning Circulation. This *conveyor belt* carries warm water from the tropics (represented by red arrows) into the North Atlantic. There, the water cools and sinks before flowing back toward the south (yellow arrows). This pattern of circulation plays an important role in regulating climate in the North Atlantic as well as the rest of the world.
