Watto News-bits The oddest precipitation...raining Diamonds on Uranus and Neptune

 

     

The Oddest Precipitation !  The high-pressure, methane-rich atmospheres of the ice giants may produce diamond hailstones.

The ice giants Uranus and Neptune get their blue hue from the presence of methane, a hydrocarbon, in their dense atmospheres – and they may also get diamond hailstones from it too. The extreme pressure and heat of the planets' atmospheres may compress methane so much that diamonds are formed and then fall toward the planets' atmospheres may compress methane so much that diamonds are formed and then fall toward the planets' rocky cores.

the Record on Earth - On July 23, 2010, a hailstone that weighed almost a kilogram and measured more than 20 centimetres in diameter fell in South Dakota.

Diamonds are just carbon but are the hardest substance on Earth.

1 kilogram has an estimated street value of $100 million.

If a diamond is 'cooked' in an oven at 763 °C, it will simply vanish.

Diamonds are 100 times more valuable than gold.

Diamonds are commonly judged by the 'four Cs': carat, clarity, colour, and cut.

A diamond is 58 times harder than the next hardest mineral on Earth.

About half of all the worlds' diamonds come from Africa.

Belgium is the international diamond trading capital of the world.

The only way to cut diamonds is with other diamonds.
