Jackstraw crystals of splendent, acicular jamesonite, to 2.3 cm in length, are associated with modified cubes of brassy yellow pyrite reaching .25 cm across. This is a MAJOR example of the species from a small find that few people are aware of, I have found. I am told it was a small pocket in the mid-1980s, and I have seen only a handful turn up on the market as old collections recycle. These simply blow away other Mexican jamesonite specimens, and most worldwide jamesonite for that matter as well, for their robust crystals and bright metallic luster. In fact, I would venture to say these are the world's best jamesonites, for my own taste. This piece has a rich smothering of splendent, metallic-gray crystals of jamesonite to 2.3 cm across, very important for the species. Comes with custom lucite base already made for the specimen.
