Astronomers have theorized that Neptune and Uranus rain diamonds since the 1980s, but it’s not like scientists could just run out and check. And the last probe to visit either planet was Voyager ...

A new study has found that "diamond rain," a long-hypothesized exotic type of precipitation on ice giant planets, could be more common than previously thought.

Diamond rain may be more common across the universe than we thought. ... have led to confusion about the conditions under which diamonds could form inside ice giants such as Uranus and Neptune.

On ice giants like Uranus and Neptune, it’s thought that the extreme pressure would compress elements like hydrogen and carbon to form solid diamonds that then fall through the atmosphere like rain.

Jan 08, 2024: Diamond rain in the universe probably more widespread than previously assumed (Nanowerk News) An international team of researchers led by Mungo Frost from SLAC National Accelerator ...

Diamond rain on Neptune and Uranus forms at a lower depth than previously thought. Copper $ 5.6045 / lb -0.44%. Brent Crude Oil $ 70.36 / bbl 1.99%. Palladium $ 1283.2 / ozt 6.71%.

Diamonds on Earth are pretty rare, despite being a girl’s best friend. But on ice giant planets like Uranus and Neptune, it is expected that diamonds rain down through the atmosphere.

Remarkably, the scientists say that diamonds produced by conditions on Neptune or Uranus could weigh millions of carats. The record for a diamond on Earth is just over 3,100 carats.
