A much better than average tri-state classic, ex John Marshall collection. Crystals to 3.6 CM on a thin matrix plate range in color from translucent ruby red to black. Pitcher Field produced huge numbers of Sphalerites 40+ years ago, it is now rare to see good ones. In fine condition, well composed and far more attractive than is typical.

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!
