[Rockhounds] "Impossibly Perfect" Crystals

[Drew]

"Neither glass nor crystal, quasicrystals have symmetries once considered to
be impossible for solids.

Now, 25 years after successfully creating artificial quasicrystals in the
lab, scientists from Princeton University and elsewhere have found perfect
quasicrystals in nature, locked inside a rock from a Russian mountain
range."
