Some of the weirdest habit Silver minerals and especially Acanthites have come out of Morocco from time to time. This is a very nice example with a sizable chain of oriented stacked octahedrons that displays very well. Somewhat crude as are all of these but undamaged and a complete floater. This came out over a decade ago. The new restrictions have cut off most everything from these great silver mines.
Proustite is a "noble" silver mineral. It is rare, sometimes beautiful, expensive and highly desirable. From the classic locations in Germany and Chile good pieces often sell for more than double their weight in gold. Recent finds in Morocco produced a lot of low end, affordable specimens but only a few fine pieces. This specimen stands out as fine, with unusually large crystals, excellent ruby color and dense coverage. The largest crystal here is about a centimeter in size, but most are smaller. The matrix is a silver rich Galena/ Acanthite. A real attractive, fine piece well below market for a good example of this "holy grail" specie!
