Images 5 of 21 - Uncut Diamond Add to My Project Save image to desktop Uncut Diamond Description: When a volcano sits dormant for periods of time, gases may seep from the cooling magma that lies beneath the volcano. As the gases rise through the rocks of the volcano, they react chemically with the minerals in the rocks and create new minerals. This slow crystallisation produced large perfectly formed crystals like diamonds. This picture shows an uncut diamond found in volcanic rock from Kimberley, South Africa.
