whoa! 
Now that's some ice!

The diamond was collected from the Karowe Mine that is located midway between two impact craters in Botswana. I am not at all surprised by this and it is further evidence to consider when prospecting for diamonds.
Take for instance the location of a similar multi-ring-dike structure (Virginia Dale) that is near the former Kelsey Lake diamond mine where significantly large gemstones have been produced. This is more support for my strong opinion that hyper-velocity impacts bring diamond bearing mantle to the Earth's surface.
Here's my Google Earth map of the location...

Wow that is a monster diamond!
I agree with your theory ASTROBLEME. After doing a bunch of research and reading about the State Line District (I have not had a chance to go there yet) my brother and I concluded that a large impact likely caused the rings and the diamond bearing material to come to the surface. Have you seen any other evidence of an impact crater, like shocked quartz or other signs?

Being that big, if you put it up to your cheek, would it be really cold to the touch?

Mike,
I haven't had access into the central core area where evidence should still remain. This is a very old structure and highly eroded so the central core may be the best bet for collecting shatter cones or tektite specimens.
