A very sharp and classic Mexican acanthite specimen that shows off the ridiculously cubic symmetry these are known for. The major frontal faces have none of the etching, weird growth effects, or hoppering that so often occurs here, presenting you with what looks like machined cubes. From the award-winning thumbnail collection of Sharon and William Panczner, author of the book Minerals Of Mexico, and last seen and exhibited in the 1960s.
