Kimberley big hole di afrika selatan..mula di gali pertengahan bulan julai 1871 mengunakan cangkul dan penyodok oleh lebih 50 ribu pekerja mencari belian..Apparently the largest ever hand-dug excavation in the world, this 1097 meter (3,599 fett) deep mine yielded over 3 tons of diamonds before being closed in 1914.
Thanks for reading & sharing New Nadia Fans
