We’ve mentioned in the past that Saturn and Jupiter might be raining diamonds. However, for the biggest diamonds we might have to travel event further. Out of our solar system scientists believe there is a planet whose mass may be as much as 1/3 diamond. Since the planet is so much larger than earth that 1/3 would equal about 2 earth masses!!!
Want even bigger? More recently astronomers have just revealed that there is a dwarf star with the mass of our own sun which might just be one large diamond. The dwarf star has the mass of our own sun but has collapsed in on itself and in the process turned itself into a gem of a star. The weight in carats of diamond is estimated at 10 billion trillion trillion.
