A very large and visually impressive gem Sphalerite with the added attraction of a scarce US locale. Most examples of this species cut from US deposits come from limited areas of Colorado, New Mexico or New York - this is one of the few Montana gems we have offered. A custom cut stone with a distinct and lovely green-yellow bodycolor. Additionally (and nicely!) there is a little reddish color zoning that adds to the spectal flash. Extremely dispersive, the cutting is absolute precision and the gem is nearly totally clean. A remarkable stone of exceptional size from this locality and a fantastic US collector's piece.
