Huebnerite and Quartz

A superb example of up to 3.8cm huebnerites with top luster. Pieces were never very common and they do display the bright red color where the edges are thinner. All but two are completely terminated on the top, some exhibiting later stage growth features where the crystals had broken in situ. Rather exceptional.

Locality: Pasto Bueno, Ancash Department, Peru
