Saturn and Jupiter may be a girl's best friend after scientists have claimed that diamonds may fall from the sky as rain to create large oceans on the giant planets.
Astrophysicists have calculated that the conditions on the two biggest planets of the solar system are enough to produce stable oceans made from diamond.
They claim that powerful lightning storms in the planets' atmospheres cause particles of carbon to form, which then drift down though the gas.
As the carbon falls, it is crushed by the enormous pressures that exist on the two planets, causing them to form dense chunks of diamond.
At even greater depths, the scientists say the diamond will eventually melt to form liquid diamond, which may then form a stable ocean layer.
Dr Kevin Baines, from the University of Wisconsin-Madison, who conducted the work along with Dr Mona Delitsky, from California speciality Engineering, said: “At the boundaries -- locations of sharp increases in density -- on Jupiter and Saturn, there may be diamond rain or diamond oceans sitting as a layer
“Previously, only Uranus and Neptune were thought to have conditions in their interiors that would allow the formation of diamond at their cores.”
Baines and Delitsky are due to present their findings to the annual meeting of the Division for Planetary Sciences of the American Astronomical Society.
They used new data from experiments on how diamond changes state at extremely high pressures temperatures.
They calculated the altitude on each planet at which diamond reaches its melting point.
They say that while on Jupiter most of the diamond material will melt to form a liquid, on Saturn there may be chunks of diamond floating around.
