This is an exceedingly rich specimen with good pedigree, containing about the most Argentopyrite you will ever see on one specimen. Argentopyrite is a rare silver species. What is particularly nice about this piece is that the crystallization is so rich it makes for a readily visible cluster of "knobs" so you don't have to look for the usual microcrystal or two. The association with gemmy red proustite crystals is an added bonus!
