    • Crystals to big to see

      No crystal pattern is visible in Coahuila, because the entire meteorite is part of a single, immense crystal. Coahuila contains very little nickel, which enabled a single crystal of the low-nickel alloy kamacite to grow until it consumed all of the original taenite alloy. Meteorites like this are called hexahedrites.
