This attractive plate features the sharp lines of superbly crystallized, large, very lustrous, tetrahedrites, to 3.25 cm in length. These crystals visibly have complicated striations that give them a lot of character and dimensionality, plus they stand out more from the matrix than you normally see in Mexican tetrahedrites. In fact, the quality is so good here, they are of a quality you associate with Peru (but the overall look is distinct). This is certainly one of the best examples we have seen, for quality... there are bigger crystals to be sure, but this association on sparkly pyrite, with dramatic individualized crystals, makes the piece.
