The Kimberley Diamond Mine also known as
the Big Hole is considered the largest hand-dug hole in the world.
Panorama of the biggest man-dug hole.
Apparently
the largest ever hand-dug excavation in the world, this 1097 meter deep
mine yielded over 3 tons of diamonds before being closed in
1914.
At the mouth of Big Hole
A sign next to the Big Hole - "If all
the diamonds recovered from the Kimberley Mine could be gathered
together they would fill three cocopans such as these.”
The photo was captured by satelites.
There's a museum near the Big Hole, which shows what the
mined and final products look like.
