Here's a 1327-atom model of two-dimensional
dendritic solidification in a droplet of liquid carbon. The atoms of
carbon which remain in the liquid state are excluded from the picture
for clarity. This type of sheet structure seems to explain both
the diffraction and high resolution

graphite onions found in presolar grains extracted from the meteorite
