Franckeite is a sulfosalt mineral known originally and still predominantly from Bolivia. These crystallized specimens seem to trickle out of the mines. This example is essentially a double ball of crystals. Like most examples, the crystals are rounded, likely from conditions at the mine. A good, rare example of this sulfosalt; much better than the massive material.
