Facts about Diamonds

Natural Diamonds are formed deep in the ground under extreme pressure. They are the second purest form of carbon coming only after Graphite as the second hardest substance known to man.

Diamonds are formed from compressed carbon molecules at up to 200km under the earth’s surface where previously existing rock gets melted by the magma and new carbon molecules are formed. These carbon molecules are then compressed at extreme pressures for billions of years until they are forced to the earth’s surface by a volcanic eruption or from some other catastrophic event.

If a Diamond is brought to the earth’s surface through a volcanic eruption, the diamonds come up through volcanic pipes or sometimes they are called Kimberlite pipes.

These volcanic pipes are currents of magma that has flowed through the volcano’s melted wall or been physically ejected through the volcanic eruption and virtually spewed from deep within the earth to the surface. Usually though they flow up in volcanic pipes at a more sedate pace.

Just because they have been ejected from deep within the earth doesn’t mean they will lie around on the ground waiting to be picked up by any passer-by.
