Take a look at this hollowed out hole in the Earth snapped by photographer Dillon Marsh. Then look closer.
Can you see the tiny speck posted on a pedestal in front of the hole at Koffiefontein Mine in South Africa?
That's what 7.6 million carats of diamonds extracted from the mine looks like in comparison to the size of the hole.
Marsh started the "For What Its Worth" project in 2014 taking pictures of copper mines and providing a visual comparison of what the amount of metal looked like in relation to the mine it was taken from.
Later in 2014, he started doing the same thing with diamond mines.
Kimberley Mine operated from 1871 - 1914 and yielded 14.5 million carats of diamonds. The representative diamond here is in the middle of the pond — look for the white speck. (Photo credit: Dillon Marsh)
"It is really just my personal curiosity about mining that lead to the start this project," the 34-year-old photographer from Cape Town, South Africa, told TheBlaze in an email. "I wanted to find a way of seeing what a mine looked like in comparison to the total amount of precious stones or metals that was extracted from it."
The purpose of the project, he wrote, is to "offer a new perspective on mining, and to encourage discourse about its merits and shortfalls."
Going forward, Marsh said he is considering looking at platinum mines in South Africa. He has already done the project with gold.
