It rains, not men, but diamonds. However, before you start bringing out large pails and containers to catch these sources of wealth, be informed that the rain of diamonds take place not on Earth but on other planets, including Saturn and Jupiter.

American scientists explained on Monday that lightning storms in the two planets will turn methane into soot that hardens when it fall into pieces of graphite and then eventually become diamonds. But these hail stones later melt because of Saturn's and Jupiter's hot cores that turn them into a liquid sea.

Dr Kevin Baines of the University of Wisconsin-Madison and NASA's Jet Propulsion Laboratory estimated that the biggest diamond would likely measure one centimeter in diameter, adding those sizes of diamond are of the size that deceased actress Elizabeth Taylor would be proud to wear.

He said about 1,000 tonnes of diamond are created yearly in Saturn. He added the basis of their theory about the diamond rain is principles of chemistry of which he is certain.

He and co-author Mona Delitsky from California Speciality Engineering shared the result of his unpublished findings at the yearly gathering of the Division for Planetary Sciences of the American Astronomical Society in Denver, Colorado.

The two explained their findings based on the latest temperature and pressure forecasts for the interiors of the two planets and new data on how carbon behaves in different conditions.

The process starts in the upper atmosphere in the thunderstorm alleys where lightning converts methane into soot. When soot falls, the pressure increased and upon reaching 1,000 miles, it becomes graphite, a sheet-like form of carbon found in pencils.

When it reaches 6,000 kilometres, the pieces of falling graphite becomes harder into diamonds, falling further for 30,000 more kilometers.

However, the catch is "Once you get down to those extreme depths, the pressure and temperature is so hellish, there's no way the diamonds could remain solid," BBC quoted Mr Baines.

But while diamonds are not forever in Saturn and Jupiter, in Uranus and Neptune these precious stones are eternal due to these planets' cooler cores.

If there is a cheap way to harvest these gems from other planets, then surely this ballad by Shirley Bassey would be earthling's theme song.
