Once upon a time, there was a massive mining pit in Eastern Siberia, Russia. At nearly 4,000 feet wide and 1,804 feet deep, the mine in its heyday extracted 2,000 kilograms of diamonds per year, a fifth of that high-quality jeweler’s stones.
In fact, production at the Mirny Mine, as it was called, was so weighted toward these superior-quality stones that diamond giant De Beers was forced to buy them to keep the market artificially inflated.

However, the mine closed in 2001, leaving a gigantic hole in the ground with layers, or levels, reminiscent of the tiered paddy fields in China.
