Tiny blobs of material trapped inside large, clear diamonds (such as this one) as they formed suggest the gems formed within pockets of liquid metal deep within Earth.
Many of those tiny blobs were long thought to be bits of graphite — like diamond, another form of pure carbon — and were thus cut away and discarded by jewelers.
As the diamond crystals form, they can enclose tiny amounts of fluid or rock from their surroundings.
The stone's noble gas content supports an extraterrestrial origin, while the presence of tiny diamonds — larger than nanodiamonds found in a common kind of meteorite called chondrites, but similar in size to diamond aggregates known to be formed by impacts — supports a cometary origin.
