Diamonds: The Journey From Mine to Ring

From its formation hundreds of kilometres below the earth’s surface to its brilliant metamorphosis into someone’s cherished engagement ring, the journey of a diamond from mine to ring can take up to 3.3 billion years.

Powerful volcanic activity then pushes the kimberlite and diamond towards the earth’s surface and are mined down the volcanic pipe - the primary sources of the world's diamond mines.
