Diamond mining companies might change the course of rivers and/or build dams to reveal riches beneath riverbeds. This move destabilizes entire ecosystems. The animals and people (especially farmers) have relied on these waterways for millennia, and when waters disappear, they must look elsewhere for survival and sustenance.

There's a lot to say about diamonds: They're forged in pressure, they're a 's best friend and, according to one of the most famous marketing taglines of all time, they're "forever." They're also ethically dubious; notorious "blood diamonds" are mined in warzones and used to fund insurgencies, leading some folks to argue that every diamond has a little bit of blood on it.

How Diamonds Are Mined (in Russia) Diamonds were formed more than 300 million years ago. Kimberlite magma formed at a depth of 20 or 25 km. Magma gradually rises along faults in the crust and when the upper layer can no longer hold back the pressure of the magma, an eruption occurs. The first such "pipes" were found in Kimberley inSouth ...

A mined diamond, therefore, is a 'natural' diamond that is formed from carbon being subjected to extreme heat and pressure deep underneath the earth's crust. To get these diamonds close enough to the surface for them to be mined, they are carried upwards in a special (and rare) form of volcanic eruption, called kimberlite eruptions.

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank.
