Peanut butter is being turned into diamonds by scientists with a technique that harnesses pressures higher than those found at the centre of the earth.

Edinburgh University experts say the feat is made possible by squeezing the paste between the tips of two diamonds creating a "stiletto heel effect".

The scientists also revealed they can turn oxygen into red crystals using the same method.

Professor Malcolm McMahon, based at the Centre for Science and Extreme Conditions at Edinburgh University, is one of the scientists involved.

He said: "Pressure can cause extraordinary changes in all kinds of materials and can create completely novel materials.

Dr Colin Pulham, who is also based at the Edinburgh University, said: "Submitting substances to extremely high pressure is a valuable means for understanding their stability.

"High pressure testing of pharmaceuticals is becoming a useful technique to screen new and existing drugs.
