How long ago were diamonds formed?
3 billion years ago
Diamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Diamonds are found at a depth of approx. 150-200km below the surface of the Earth.

Are there still diamond mines to be found?
There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90\% of global supply. Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action.
What is involved in diamond mining?
Locating deposits of diamond ore is the first step in diamond mining. Identifying a pipe opening or deposit is always the first thing involved in diamond mining. Sometimes this is based on chance findings or past successes in a certain area. Usually, though, it is deduced according to geological expertise.
How are diamonds mined from the Earth?
When volcanic activity happens deep within the sea, diamonds are brought closer to the surface.The miners wait for diamonds near the earth’s surface to be washed down the river beds and beaches. The diamonds are normally brought to the surface by erosion together with strong winds and waves.
