What kind of rock is a diamond found in?
kimberlite
Diamond is only formed at high pressures. It is found in kimberlite, an ultrabasic volcanic rock formed very deep in the Earth’s crust.

Can you mine your own diamonds?
The only public diamond mine in the world, Crater of Diamonds offers you a one-of-a-kind adventure – the opportunity to hunt for real diamonds and to keep any mineral you find. You’ll search over a 37-acre plowed field – the eroded surface of an ancient, diamond-bearing volcanic pipe.

What does kimberlite look like?
kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).
Can you pan for diamonds?

How can you tell if a rock is a diamond?
The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.

How long do diamonds take to form?
between 1 billion and 3.3 billion years
The Natural Diamond Process
Due to the immense pressure that is present in this part of the earth, as well as the extreme temperatures, a diamond gradually begins to form. The entire process takes between 1 billion and 3.3 billion years, which is approximately 25% to 75% of our earth’s age.
