The world`s most amazing holes
1. Mirny diamond mine - Siberia
I`m pretty sure most people have seen this one. it`s an absolute beast and holds the title of largest open diamond mine in the world. at 525 metres deep with a top diameter of 1200 metres thereâ`s even a no-fly zone above the hole due to a few helicopters being sucked in.
