BPM 37093 is a pulsating variable white dwarf star and is about 50 light years away from Earth and is about 2/3 the diameter. It's thought to be composed of mainly carbon and oxygen, with a hydrogen atmosphere. It was predicted in the '60s that as white dwarfs cool they would crystallize from the center out, and to test this hypothesis scientists studied BPM 37093's pulses to gain insight into it's inner structure. Based on their observations they estimated that BPM 37093 is about 90% crystallized, making it potentially the largest diamond ever found.
It's carat-weight is estimated to be 10 billion trillion trillion carats. That's 10 * 10^33 carats or a total crystalline mass of more than 5×10^29 kilograms.
It's nicknamed Lucy, after the Beatles song Lucy in the sky with diamonds.
50 light years is next door. Get a space ship.
