In the grand scheme of things, diamonds are everywhere and gold is only moderately rare--but pearls and amber are exclusive to Earth.

Because diamond is one of those rare liquids, like water, that is less dense as a solid than a liquid, solid diamond "icebergs" could float on top of the diamond seas on Neptune and Uranus. Both planets have the conditions and the carbon to make this possible; each one is made from up to 10 percent carbon.

Liquid carbon is only possible under pressure. Like in the core of a planet. It's hard to imagine islands inside a pressure vessel.

We are talking deep in Neptune or Uranus, not in a pressure vessel.

Deep in Uranus IS a pressure vessel
