It's possible that diamonds could stud not just the metaphorical skies touted in pop songs, but Saturn and Jupiter's skies, as well
On Earth, diamonds bankroll dictatorships and criminal syndicates and furnish a multibillion dollar industry that touts the jewels as promises of love.
On Jupiter and Saturn, diamonds don't do any of this. But their mere theoretical presence in these two planet's skies is as enthralling a surprise to scientists as a diamond ring is to an enthusiastic bride-to-be, or to a crook dreaming of big profits from the little gem.
While diamonds have long been believed to salt the cold planets Uranus and Neptune, there had been little work on if the gems could be formed on the hotter planets with more pressurized cores, let alone exist in solid form. Most of the data had suggested that this was improbable: Jupiter and Saturn are methane poor (methane yields carbon, which is what diamonds are made of) and have cores at such galling pressures that diamond would not seem to exist there.
