Franckeite is difficult to obtain in any size, but anything larger than a thumbnail is particularly scarce.  This is a spectacular miniature, with reasonably large crystals.

This is a very rare sulfosalt, which has only been recently available from this mine and the San Jose (on the other side of the same mountain), and this is a prime example of the species.
