Diamonds are created deep under the surface of the Earth in the mantle.
This happens around 140-190km down where the heat and pressure are high enough.
Diamonds are transported to the Earth’s surface by volcanic action under continental crust in kimberlite pipes.
Diamonds are found in the earths surface in deposits of kimberlite (rock) known as kimberlite pipes.
Diamonds can be mined direct from kimberlite pipes called open pit mines.
Diamonds can also be found on flood plains where they have been eroded from the kimberlite by rivers.
Diamonds are used as gemstones in jewellery due to their light reflecting properties and beauty.
Diamonds are also used in industry for their hard properties in processes such as cutting of other materials.
We have found out how diamonds are formed, mined and used but what is the missing link from our story?
Discuss in your pairs where you think the diamonds might be transported to and traded/sold?
When diamonds are mined they must also be prepared for use, this preparation is called cutting and polishing.
Following cutting and polishing the diamonds are transported to somewhere they can be sold or traded.
Antwerp in Belgium has historically been extremely important to the diamond industry.
Even though this industry has recently decreased 70% of the world’s diamonds still pass through Antwerp, Belgium to be traded (sold).
Many people even sent their diamonds to Antwerp to be safeguarded during WW2.
